The AVO-8A3-B-P essentially acts as a high-current, high-speed switch for the output of a user-supplied DC power supply. The AVO-8A3-B-P is installed between the DC power supply and the load. The signal timing is controlled by the AVO-8A3-B-P, and the amplitude (output voltage) is controlled by the DC power supply. Avtech can recommend suitable DC power supplies for particular applications, if you do not already have one. OUT- AVTECH AVO-8A3-B-P VOUT ≈ VDC - 3V IOUT ≈ (VOUT - VDIODE) / (RSERIES + 0.01 Ohms) VDC Duty Cycle = Pulse Width x Frequency IAVG = IOUT x Duty Cycle ∆VOUT = IOUT × Pulse Width / C red cable OUT+ IAVG black cable AC POWER USER-SUPPLIED DC POWER SUPPLY, 0 to 53V C = 0.17 Farads + Power Supply Capacitance GND (-) Diode (device under test) DC IN (+) GND IOUT OUT GND VOUT OSCILLOSCOPE Pulse Width OUT AC POWER ∆VOUT VOUT scope probe CHANNEL A RSERIES SYNC OUTPUT probe ground clip TRIG INPUT The output pulse amplitude (voltage) is controlled by the user-supplied high-current DC lab power supply that is connected to the AVO-8A3-B-P (see the diagram above). The AVO-8A3-B-P instrument acts as a high-efficiency, high-speed switch that connects the DC lab power supply to the load during the output pulse duration. The output is shorted to ground between pulses. The output pulse voltage amplitude is approximately equal to the lab power supply voltage minus 3 Volts. The lab power supply must be capable of supplying at least the average value (I AVG) of the peak current supplied to the load 7 (IOUT). IAVG, IOUT, pulse width (PW) and frequency are related as shown in the diagram. Protective circuits monitor the lab power supply voltage level and the output circuit temperature and will automatically disable the triggering of the output stage if either the applied voltage or temperature exceed rated values. The AVO-8A3-B-P is voltage pulser. A non-inductive resistor must be connected in series with the diode under test to limit the current to the maximum rated current (or less). The AVO-8A3-B-P will provide up to 50A to a load impedance as low as 1 Ohms. The AVO-8A3-B-P can operate at duty cycles of up to 80% in pulse mode, and 100% and DC mode. For wide pulse width (> 1 ms) applications the current rating of the lab power supply should be near the desired peak output load current, particularly if low output pulse droop is required. However, for low duty cycle / narrow pulse applications the current rating of the lab power supply may be considerably less than the desired peak load current because the large capacitance present in the AVO-8A3-B-P output circuit (170000 uF typically) provides the necessary high peak pulse current. The pulse repetition frequency is variable from 1 Hz to 1 kHz using the internal oscillator. A delay control and a sync output are provided for oscilloscope triggering purposes. A pushbutton is provided for one-shot operation. The units can also be triggered externally using a TTL-level pulse. The AVO-8A3-B-P includes a monitor output option that provides an attenuated coincident replica of the main output current pulse. IEEE-488.2 GPIB and RS-232 control of pulse width, pulse repetition frequency, and delay is provided. These models include a front-panel keypad and adjust knob control of the output pulse parameters, along with a four line 40-character back-lit LCD display of the pulse width, pulse repetition frequency and delay. (Note that the DC power supply must be equipped with a GPIB feature, if you wish to remotely control the amplitude.) Optional telnet or web-based remote control is also available (http://www.avtechpulse.com/options/tnt), for control over local area networks or the internet. The AVO-8A3-B-P offers an optional current limit feature. This function will disable the output if the current exceeds a set level. The response time of the limit circuit is < 5 us. The trip level may be set from the front panel or by computer command. If the limit circuit is tripped the user must re-enable the output from the front panel or by computer command. Visit the application note area of the Avtech web site (http://www.avtechpulse.com/appnote) for general applications assistance. This instrument is intended for use in research, development, test and calibration laboratories by qualified personnel. 8 SPECIFICATIONS Model1: AVO-8A3-B Amplitude, voltage: (controlled by the DC power supply) 0 to 50 Volts Maximum output current: (for all output voltages) 50 Amps Typical minimum load impedance, RL : (required to limit output current) 11 Pulse width (FWHM): 1Ω 2 us to 1 second, and DC5.

Connectors (DC Power in): 6 mm plug / 4 mm sockets6 (+ red, - black) Connectors (Output): Positronic (www.positronic.com) female connector12 Output cabling: User-supplied, or use optional -AK9 accessory kit (described below). Optional recommended accessory kits8: -AK3 option: Provides two 1 m cables (1 red, 1 black) with 6mm safety sockets 8, and two 6mm safety plug to M6 stud adapters7. Recommended for connecting AVO-8 units to the DC power supply. -AK9 option: Provides one AV-HLZ1-100 cable (100 cm length, Z0 = 1 Ohm. This transmission line cable matches low impedance loads without degrading the signal rise and fall times significantly. The chassis end of the cable is terminated with a Positronic male connector13 and the load end is terminated with a Positronic female connector12). Also provides an adapter which mates to the end of this cable, and provides the output on two identical contact posts into which M6x1 threaded screws may be screwed to a maximum depth of 15 mm. This cable is not required to connect to the AV-HTL-xxx-HLZ series resistors – these resistors (ordered separately) include their own cabling. Suggested series resistor: Power requirements: Cooling: Dimensions: Rack-mount kit: Chassis material: Temperature range: Avtech AV-HTL-1R0-HLZ DC4: 0 to 52 V, > 50 Amp AC: 100 - 240 Volts, 50 - 60 Hz Self-contained fan. 138 mm x 430 mm x 425 mm, 5.5” x 17” x 16.8” Add the suffix -R6 to the model number to include 19" rack mount kit. Anodized aluminum, with blue plastic trim +5°C to +40°C 1) -B suffix indicates IEEE-488.2 GPIB and RS-232 control of pulse width, PRF and delay. (See http://www.avtechpulse.com/gpib for details). 2) Indicate desired polarity by suffixing the model number with -P or -N (i.e. positive or negative). 3) Add the suffix -TNT to the model number to specify the Internet control (Telnet and Web) option. 4) Requires a user-supplied DC power supply. Avtech suggests Xantrex as a source of DC power supplies (http://www.xantrex.com). Contact Avtech for recommendations about DC power supplies appropriate for your application. The cables for connecting the external DC power supply are not included with the standard model. 6 mm plug to 6 mm plug cables are available in the optional -AK3 accessory kit. These may or may not be suitable for your power supply, depending on the power supply's connectors. It is possible to cut and strip the ends of the optional accessory cables, and to attach other terminations. Multi-Contact (http://www.multi-contact.com or http://www.multi-contact-usa.com) can supply 6 mm plug to cable lug cables, and other configurations. 5) When externally triggered, the output pulse width can be controlled by the front panel controls (or computer command), or it can be set to follow the input pulse width (i.e., PW IN=PW OUT mode). 9 6) Multi-Contact (http://www.multi-contact.com or http://www.multi-contact-usa.com) ID/S6AR-N-B4S series, or similar. 7) Multi-Contact (http://www.multi-contact.com or http://www.multi-contact-usa.com) SLK616-AR/BGG series, or similar. 8) Add the suffix(es) -AK3 and/or -AK9 as appropriate, to the model number to include the accessory kit(s). 9) Valid for non-inductive loads of resistance RL (the specified minimum load impedance) installed directly on the output connectors (i.e., zero cable length) using low-inductance adapters, or installed directly on the end of a AV-HLZ1-100 cable plugged into the output connector. Inductive loads or cables will degrade the rise and fall times. Lower load resistances may also degrade the rise and fall times (since the inductive time constant is given by τ = L / R). 10) Add the suffix -TRIP to the model number to specify the current limit function. Units without this option will still have an over-current protection feature, but the trip level will be non-adjustable and set 20% above the maximum rated current, approximately. 11) The load impedance can be reduced below these values, as long as the maximum current rating is observed. Most diode loads will require some series resistance to be added to limit the current. 12) Positronic part number GG8888F1, with four GGFIT00MS/AA high-current contacts. The inner two contacts carry the signal, and the outer two carry the ground lines. 13) Positronic part number GG8888M1, with four GGMIT00MS/AA high-current contacts. The inner two contacts carry the signal, and the outer two carry the ground lines. 14) Up to 100%, if externally triggered and the PW IN = PW OUT mode is enabled. 10 REGULATORY NOTES FCC PART 18 This device complies with part 18 of the FCC rules for non-consumer industrial, scientific and medical (ISM) equipment. This instrument is enclosed in a rugged metal chassis and uses a filtered power entry module (where applicable). The main output signal is provided on a shielded connector that is intended to be used with shielded coaxial cabling and a shielded load. Under these conditions, the interference potential of this instrument is low. If interference is observed, check that appropriate well-shielded cabling is used on the output connectors. Contact Avtech ([email protected]) for advice if you are unsure of the most appropriate cabling. Also, check that your load is adequately shielded. It may be necessary to enclose the load in a metal enclosure. If any of the connectors on the instrument are unused, they should be covered with shielded metal “dust caps” to reduce the interference potential. This instrument does not normally require regular maintenance to minimize interference potential. However, if loose hardware or connectors are noted, they should be tightened.

The owner must ensure that operators are prevented access and/or are insulated from every connection point. In some cases, connections must be exposed to potential human contact. Operators must be trained to protect themselves from the risk of electric shock. This instrument is intended for use by qualified personnel who recognize shock hazards and are familiar with safety precautions required to avoid possibly injury. In particular, operators should: 1. Keep exposed high-voltage wiring to an absolute minimum. 15 2. Wherever possible, use shielded connectors and cabling. 3. Connect and disconnect loads and cables only when the instrument is turned off. 4. Keep in mind that all cables, connectors, oscilloscope probes, and loads must have an appropriate voltage rating. 5. Do not attempt any repairs on the instrument, beyond the fuse replacement procedures described in this manual. Contact Avtech technical support (see page 2 for contact information) if the instrument requires servicing. Service is to be performed solely by qualified service personnel. ENVIRONMENTAL CONDITIONS This instrument is intended for use under the following conditions: 1. 2. 3. 4. indoor use; altitude up to 2 000 m; temperature 5 °C to 40 °C; maximum relative humidity 80 % for temperatures up to 31 °C decreasing linearly to 50 % relative humidity at 40 °C; 5. Mains supply voltage fluctuations up to ±10 % of the nominal voltage; 6. no pollution or only dry, non-conductive pollution. 16 FUSES This instrument contains four fuses. All are accessible from the rear-panel. Two protect the AC prime power input, and two protect the internal DC power supplies. The locations of the fuses on the rear panel are shown in the figure below: Fuses #1 and #2 (AC fuses) Fuse #4 (DC fuse) Fuse #3 (DC fuse) AC FUSE REPLACEMENT To physically access the AC fuses, the power cord must be detached from the rear panel of the instrument. The fuse drawer may then be extracted using a small flat-head screwdriver, as shown below: Pry out the fuse drawer using a screwdriver. Fuse Drawer 17 DC FUSE REPLACEMENT The DC fuses may be replaced by inserting the tip of a flat-head screwdriver into the fuse holder slot, and rotating the slot counter-clockwise. The fuse and its carrier will then pop out. FUSE RATINGS The following table lists the required fuses: Fuses Nominal Mains Voltage #1, #2 (AC) 100-240V #3 (DC) N/A #4 (DC) N/A Rating 0.5A, 250V, Time-Delay 1.6A, 250V, Time-Delay Recommended Replacement Part Case Size Littelfuse Part Digi-Key Stock Number Number 5×20 mm 0218.500HXP F2416-ND 5×20 mm 021801.6HXP F2424-ND Not used. A spare 1.6A fuse is installed here. The recommended fuse manufacturer is Littelfuse (http://www.littelfuse.com). Replacement fuses may be easily obtained from Digi-Key (http://www.digikey.com) and other distributors. 18 FRONT PANEL CONTROLS 1 2 5 4 3 1. POWER Switch. This is the main power switch. When turning the instrument on, there may be a delay of several seconds before the instrument appears to respond. 2. OVERLOAD Indicator. When the instrument is powered, this indicator is normally green, indicating normal operation. If this indicator is yellow, an internal automatic overload protection circuit has been tripped. If the unit is overloaded (by operating at an exceedingly high duty cycle or by operating into a very low impedance), the protective circuit will disable the output of the instrument and turn the indicator light yellow. The light will stay yellow (i.e. output disabled) for about 5 seconds after which the instrument will attempt to re-enable the output (i.e. light green) for about 1 second. If the overload condition persists, the output will be disabled again (i.e. light yellow) for another 5 seconds. If the overload condition has been removed, the instrument will resume normal operation. This overload indicator may flash yellow briefly at start-up. This is not a cause for concern. Note that the output stage will safely withstand a short-circuited load condition. 3. SYNC OUT. This connector supplies a SYNC output that can be used to trigger other equipment, particularly oscilloscopes. This signal leads (or lags) the main output by a duration set by the "DELAY" controls and has an approximate amplitude of +3 Volts to RL > 50Ω with a pulse width of approximately 100 ns. 4. LIQUID CRYSTAL DISPLAY (LCD). This LCD is used in conjunction with the keypad to change the instrument settings. Normally, the main menu is displayed, which lists the key adjustable parameters and their current values. The “Programming Manual for -B Instruments” describes the menus and submenus in detail. 19 5. KEYPAD. Control Name MOVE CHANGE ×10 ÷10 +/EXTRA FINE ADJUST Function This moves the arrow pointer on the display. This is used to enter the submenu, or to select the operating mode, pointed to by the arrow pointer. If one of the adjustable numeric parameters is displayed, this increases the setting by a factor of ten. If one of the adjustable numeric parameters is displayed, this decreases the setting by a factor of ten. If one of the adjustable numeric parameters is displayed, and this parameter can be both positive or negative, this changes the sign of the parameter. This changes the step size of the ADJUST knob. In the extrafine mode, the step size is twenty times finer than in the normal mode. This button switches between the two step sizes. This large knob adjusts the value of any displayed numeric adjustable values, such as frequency, pulse width, etc. The adjust step size is set by the "EXTRA FINE" button. When the main menu is displayed, this knob can be used to move the arrow pointer. 20 REAR PANEL CONTROLS 1 9 5 4 3 GND (-) OUT GATE DC IN (+) TRIG RS-232 AMP GPIB 11 6 7 8 10 2 1. AC POWER INPUT. An IEC-320 C14 three-pronged recessed male socket is provided on the back panel for AC power connection to the instrument. One end of the detachable power cord that is supplied with the instrument plugs into this socket. 2. AC FUSE DRAWER. The two fuses that protect the AC input are located in this drawer. Please see the “FUSES” section of this manual for more information. 3. DC FUSES. These two fuses protect the internal DC power supplies. Please see the “FUSES” sections of this manual for more information. 4. GATE. This TTL-level (0 and +5V) logic input can be used to gate the triggering of the instrument. This input can be either active high or active low, depending on the front panel settings or programming commands. (The instrument triggers normally when this input is unconnected). When set to active high mode, this input is pulleddown to ground by a 1 kΩ resistor. When set to active low mode, this input is pulledup to +5V by a 1 kΩ resistor. 5. TRIG. This TTL-level (0 and +5V) logic input can be used to trigger the instrument, if the instrument is set to triggering externally. The instrument triggers on the rising edge of this input. The input impedance of this input is 1 kΩ. (Depending on the length of cable attached to this input, and the source driving it, it may be desirable to add a coaxial 50 Ohm terminator to this input to provide a proper transmission line termination. The Pasternack (www.pasternack.com) PE6008-50 BNC feed-thru 50 Ohm terminator is suggested for this purpose.) When triggering externally, the instrument can be set such that the output pulse 21 width tracks the pulse width on this input, or the output pulse width can be set independently. Do not exceed a repetition rate of 1 kHz when triggering externally. Excessive repetition rates may cause over-heating internally, and possible damage the instrument. 6. GPIB Connector. A standard GPIB cable can be attached to this connector to allow the instrument to be computer-controlled. See the “Programming Manual for -B Instruments” for more details on GPIB control. 7. RS-232 Connector. A standard serial cable with a 25-pin male connector can be attached to this connector to allow the instrument to be computer-controlled. See the “Programming Manual for -B Instruments” for more details on RS-232 control. 8. DC IN (+) Connector. This power input connector must be connected to the positive (+) output of the user-supplied external DC power supply. This connector will accept 6 mm safety sockets, or 4 mm "banana" plugs. (6 mm safety sockets will have considerably higher current capability). Beware that the 6 mm cables "lock" into the mating adapters. To release the lock, push the cable inwards FIRST, and THEN pull it out of the adapter. The cable will not be released if you simply pull on it. 9. GND (-) Connector. This power input connector must be connected to the negative (-) output of the user-supplied external DC power supply. This connector will accept 6 mm safety sockets, or 4 mm "banana" plugs. (6 mm safety sockets will have considerably higher current capability). Beware that the 6 mm cables "lock" into the mating adapters. To release the lock, push the cable inwards FIRST, and THEN pull it out of the adapter. The cable will not be released if you simply pull on it. 10. OUT/GND Connector. This is the main output connector (Positronic part number GG8888F1, with four GGFIT00MS/AA high-current contacts). The inner two contacts carry the signal, and the outer two carry the ground lines. The optional AV-HLZ1-100 cable or the AV-HLZAX test load may be plugged into this connector (these items are supplied with the -AK9 accessory kit option). Alternatively, the user may construct their own mating connector, by ordering Positronic (www.positronic.com) part number GG8888M1, with four GGMIT00MS/AA high-current contacts. 11. AMP Connector. This is a current monitor output. This output provides a voltage waveform that is proportional to the current waveform on the output. The monitor relationship is: VMON = IOUT × 1V/10A, for a load of > 1 kΩ. (The monitor output can also drive a 50Ω load, but the output voltage will be reduced by a factor of 2. This output is short-circuit protected.) The monitor loses accuracy for pulse widths of 10 us and less. 22 PULSE GENERATOR TIMING BASIC PULSE CONTROL This instrument can be triggered by its own internal clock or by an external TTL trigger signal. In either case, two output channels respond to the trigger: OUT and SYNC. The OUT channel is the signal that is applied to the load. Its amplitude and pulse width are variable. The SYNC pulse is a fixed-width TTL-level reference pulse used to trigger oscilloscopes or other measurement systems. When the delay is set to a positive value the SYNC pulse precedes the OUT pulse. When the delay is set to a negative value the SYNC pulse follows the OUT pulse. These pulses are illustrated below, assuming internal triggering and positive delay: SYNC OUT (generated by the internal oscillator) 100 ns, FIXED 3V, FIXED DELAY > 0 PULSE WIDTH AMPLITUDE, SET BY EXTERNAL POWER SUPPLY MAIN OUTPUT If the delay is negative, the order of the SYNC and OUT pulses is reversed: 100 ns, FIXED SYNC OUT (generated by the internal oscillator) 3V, FIXED DELAY < 0 PULSE WIDTH MAIN OUTPUT AMPLITUDE, SET BY EXTERNAL POWER SUPPLY The next figure illustrates the relationship between the signals when an external TTLlevel trigger is used: 23 > 50 ns TRIG (external input) TTL LEVELS (0V and 3V-5V) PROPAGATION DELAY (FIXED) 100 ns, FIXED SYNC OUT 3V, FIXED DELAY > 0 PULSE WIDTH AMPLITUDE, SET BY EXTERNAL POWER SUPPLY MAIN OUTPUT As before, if the delay is negative, the order of the SYNC and OUT pulses is reversed. The last figure illustrates the relationship between the signal when an external TTL-level trigger is used in the PW IN=PW OUT mode. In this case, the output pulse width equals the external trigger’s pulse width (approximately), and the delay circuit is bypassed: PW IN TRIG (external input) TTL LEVELS (0V and 3V-5V) PROPAGATION DELAY (FIXED) PW OUT ≈ PW IN MAIN OUTPUT AMPLITUDE, SET BY EXTERNAL POWER SUPPLY The delay, pulse width, and frequency (when in the internal mode), of the main output pulse can be varied with front panel controls or via the GPIB or RS-232 computer interfaces. In all modes, the amplitude of the main output pulse is controlled by the DC voltage applied across the DC IN (+) and GND (-) connectors on the rear panel. This voltage is generated by the user-supplied external DC power supply. Do not exceed a repetition rate of 1 kHz when triggering externally. Excessive repetition rates may cause over-heating internally, and possible damage the instrument. 24 TRIGGER MODES This instrument has four trigger modes: • Internal Trigger: the instrument controls the trigger frequency, and generates the clock internally. • External Trigger: the instrument is triggered by an external TTL-level clock on the back-panel TRIG connector. • Manual Trigger: the instrument is triggered by the front-panel “SINGLE PULSE” pushbutton. • Hold Trigger: the instrument is set to not trigger at all. These modes can be selected using the front panel trigger menu, or by using the appropriate programming commands. (See the “Programming Manual for -B Instruments” for more details.) PULSE WIDTH MODES This instrument has two pulse width modes: • Normal: the instrument controls the output pulse width. • PW IN=PW OUT: the output pulse width equals the pulse width of the trigger signal on the “TRIG” connector. The instrument must be in the external trigger mode. These modes can be selected using the front panel pulse width menu, or by using the appropriate programming commands. (See the “Programming Manual for -B Instruments” for more details.) GATING MODES Triggering can be suppressed by a TTL-level signal on the rear-panel GATE connector. The instrument can be set to stop triggering when this input high or low, using the frontpanel gate menu or the appropriate programming commands. This input can also be set to act synchronously or asynchronously. When set to asynchronous mode, the GATE will disable the output immediately. Output pulses may be truncated. When set to synchronous mode, the output will complete the full pulse width if the output is high, and then stop triggering. No pulses are truncated in this mode. 25 CONNECTING TO A POWER SUPPLY The basic connection arrangement for the AVO-8A3-B-P is shown below. The AVO8A3-B-P must be connected to a user-supplied external DC power supply. Specifically, the "DC IN (+)" rear-panel connector (which is identified with a red ring) should be connected to the positive output of the power supply, and the "GND (-)" rear-panel connector (which is identified with a black ring) should be connected to the negative output of the power supply. If the AVO-8A3-B-P has been ordered with the -AK3 accessory kit, the included red and black cables are suggested for this purpose. OUT- AVTECH AVO-8A3-B-P VOUT ≈ VDC - 3V IOUT ≈ (VOUT - VDIODE) / (RSERIES + 0.01 Ohms) VDC Duty Cycle = Pulse Width x Frequency IAVG = IOUT x Duty Cycle ∆VOUT = IOUT × Pulse Width / C red cable OUT+ IAVG black cable AC POWER USER-SUPPLIED DC POWER SUPPLY, 0 to 53V C = 0.17 Farads + Power Supply Capacitance GND (-) Diode (device under test) DC IN (+) GND IOUT OUT GND VOUT OSCILLOSCOPE Pulse Width OUT AC POWER ∆VOUT VOUT scope probe CHANNEL A RSERIES SYNC OUTPUT probe ground clip TRIG INPUT Possible DC power supplies for use with the AVO-8A3-B-P are listed in Appendix A. GROUNDING ISSUES To avoid ground loops that might distort measurements, the power supply terminals (OUT- and OUT+) should not normally be connected or jumpered to any ground terminals on the power supply chassis. Instead, ground the "GND" output contacts by connecting them to the measurement system ground (which, in turn, must be 26 connected to earth ground). The "GND" connectors on the rear panel are not internally connected to the chassis or AC grounds. (The “GND” connectors are connected to each other internally, however.) The system may be grounded at the power supply instead, if this less-ideal configuration is more practical for the user, but the rising and falling edges of the pulse may be slightly distorted by ground-loop effects. The GND output contacts must be connected (by the user) to earth ground, preferably through the measurement system ground. In the diagram above, the output GND terminals are connected to the ground clip on the oscilloscope probe, providing the connection to the measurement system ground and earth ground. USING THE 6 mm CONNECTORS The four 6 mm connectors on the rear panel are designed to accept cables terminated with 6 mm sockets or 4 mm "banana" plugs. 4 mm "banana" plug cables are quite common, and are used with many lower-current DC power supplies. However, if you intend to operate at high average currents (I AVG > 15 Amps) then they are probably unsuitable, and 6 mm socket cables should be used instead. The higher-current 6 mm socket cables are less common. See the "AK3 Accessory Kit Section" for details about suitable cables and adapters. Beware that the 6 mm cables "lock" into the mating adapters. To release the lock, push the cable inwards FIRST, and THEN pull it out of the adapter. The cable will not be released if you simply pull on it. A typical power supply to pulser connection is shown below. 27 The next photo shows how 4 mm "banana" cables will also mate to the DC power input connectors: 28 THERMAL NOTES Due to the very high average and peak currents that can be produced by the AVO8A3-B-P, the power supply cables and connectors may become warm to the touch. However, they should NOT become uncomfortable to the touch (> 50°C). If they do, turn off the instrument and re-consider your cabling scheme or reduce the output duty cycle. 29 AK3, AK4, AK5 ACCESSORY KITS KIT CONTENTS The AK3, AK4, and AK5 accessory kits contain cables terminated with 6 mm safety sockets, and matching 6 mm safety plug to M4 stud adapters. The AK3 kit contains two cables (one red, one black) and two adapters (one red, one black). The AK5 kit contains two cables (one yellow, one green) and two adapters (one yellow, one green). The AK4 kit contains four cables (one each of red, black, yellow, and green) and four adapters (one each of red, black, yellow, and green). The AK4 kit is shown below: The cable colors (red, black, yellow, or green) refer to the identifying bands on the end of the cables. The bulk of the cable is red for the “red” cable, black for the “green” and “black” cables. The bulk of the “yellow” cable shown above is black, but it may be green/yellow stripe combination instead, due to the manufacturer's (Multi-Contact) variations. 30 SPECIFICATIONS Type Series 1 meter Cable Multi-Contact with 6 mm SLK616-AR/BGG safety sockets 6 mm safety plug to M4 stud adapter Multi-Contact ID/S6AR-N-B4S Color Multi-Contact Part Number Red 15.2502-100-22 Black 15.2502-100-21 Yellow 15.2502-100-24* Green 15.2502-100-25* Red 14.0034-22 Black 14.0034-21 Yellow 14.0034-24 Rated Current (DC) Rated Current (1 sec pulse) 100 A 1200 A 100 A 1200 A Green 14.0034-25 * May be a “special order” part for Multi-Contact. GENERAL INFORMATION The red and black cables are typically used to connect an Avtech pulse generator to a DC power supply (red = +, black = -). If your DC power supply does not provide its outputs on 6 mm safety plugs, then it may be necessary to use the red and black 6 mm safety plug to M4 stud adapters to build an appropriate connection to your power supply. The yellow and green cables are typically plugged directly into the matching 6 mm plug connectors on the rear panel of an Avtech high-current pulse generator. The yellow and green 6 mm safety plug to M4 stud adapters are provided so that an appropriate connection may be made to your load. Beware that these 1 meter cables have an inductance of approximately 0.6 uH, and they may not be appropriate for high-speed use. The inductance will introduce an inductive time constant of τ = L / R, where L = 0.6 uH, and R = your load resistance. It may be necessary to trim the cables for faster speeds. The cables "lock" into the mating adapters. To release the lock, push the cable inwards FIRST, and THEN pull it out of the adapter. The cable will not be released if you simply pull on it. REPLACEMENT PARTS AND OTHER ACCESSORIES The parts in this accessory kit, and other mating accessories, are available individually from the manufacturer, Multi-Contact (see http://www.multi-contact-usa.com or http://www.multicontact.com). 31 CONNECTING TO THE LOAD The main output connector is a Positronic part number GG8888F1, with four GGFIT00MS/AA high-current contacts. The inner two contacts carry the signal, and the outer two carry the ground lines. The supplied AV-HLZ1-100 cable or the AV-HLZAX test load may be plugged into this connector. Alternatively, the user may construct their own mating connector, by ordering Positronic (www.positronic.com) part number GG8888M1, with four GGMIT00MS/AA high-current contacts. Note the alignment grooves. Mating connectors must be positioned appropriately. Alignment grooves Ground Out Out Ground AV-HLZ1-100 CABLE One AV-HLZ1-100 cable is provided with the AVOZ-8A3-B-P. One end of the cable mates to the rear-panel OUT connector. The cable is specially designed to have a transmission line characteristic impedance (Z0) of approximately 1 Ohm, to minimize distortions and reflections. The cable may be attached to the OUT connector simply by inserting the male end of the cable into the OUT connector, taking care to align the alignment grooves. The jack screws may be used to secure the cable to the connector. An attached cable is shown below: 32 AV-HLZAX ADAPTER An AV-HLZAX adapter is provided with the AVOZ-8A3-B-P. The AV-HLZAX adapter may be plugged directly into the rear-panel OUT connector, or it may be plugged into the end of the AV-HLZ1-100 cable. Both configurations are shown below (the green resistors shown in the photos are not included): 33 In both cases, the OUTPUT signal is provided on the NARROW copper strip, and the GROUND is provided on the WIDE copper strip. This is shown schematically below: Narrow Copper Strip = OUT Wide Copper Strip = GROUND End View of AV-HLZA The load may be installed between these two strips, as shown in a side view: 34 Plugs Narrow Copper Strip = OUT Load Resistance Wide Copper Strip = GROUND Side View of AV-HLZA The copper strips may be removed entirely, if the user wishes to construct their own load attachment arrangement. If the copper strips are removed, the OUT and GROUND signals may be accessed using the four high-current posts, which are terminated with M6-1.0 internal threads. An M6-1.0x12 screw should be used to attach cabling to each of the four posts. The inner two posts carry the OUT signal, and the outer two posts carry the ground: Inner Posts = OUT Outer posts = GROUND End View of AV-HLZA, With Copper Strips Removed For maximum current carrying capability (i.e., least resistance), all four posts should be used. THERMAL NOTES Due to the very high average and peak currents that can be produced by the AVO8A3-B-P, the output cables and connectors may become warm to the touch. However, 35 they should NOT become uncomfortable to the touch (> 50°C). If they do, turn off the instrument and re-consider your cabling scheme or reduce the output duty cycle. 36 SELECTING AN APPROPRIATE SERIES RESISTANCE The AVO-8A3-B-P is a voltage pulser. A resistance must be present in the load to limit the current to 50 Amps or lower. If your load or device under test does not already have a current-limiting resistance, then additional resistance must be added in series with your device. This resistance is typically 1.0 Ohms (i.e., 50V / 50A = 1.0 Ω). The power dissipated by the resistor may be as high as 5000W (depending on the voltage and duty cycle). It may be necessary to water-cool the resistor. The power dissipated in the resistor is given by P = I2 × R × PW / T, where “I” is the current, “R” is the resistance, “PW” is the pulse width, and “T” is the pulse period (1/frequency). It is very important to construct the series resistance so that the parasitic inductance is very low, otherwise the rise and fall times will be noticeably degraded. In general, wirewound resistors should be avoided due to their inductive design. Paralleling resistors is strongly recommended, since a parallel array of N resistors will reduce the overall parasitic inductance by a factor of N, compared to a single resistor. For low average power applications (< 30 W), Avtech suggests using multiple Ohmite (http://www.ohmite.com) ceramic composition resistors in parallel. The Ohmite OX, OY, AW, AX, AY, and AZ series are all very rugged and low inductance. For high average power applications, consider using the Ohmite TAP600 or TAP1000 heat-sinkable power resistors. The parasitic resistance associated with these resistors is on order of 80 nH. Several should be used in parallel, and be heatsunk on a watercooled plate. (Suitable cooling plates are manufactured by D6 Industries, http://www.d6industries.com). Avtech can construct high-power loads and series resistances for particular applications. Contact Avtech ([email protected]) with your requirement. LOW IMPEDANCE LOADS AND RISE TIME The rise time specification of 0.5 us is valid for non-inductive 1.0 Ohm loads installed directly on the output connectors (i.e., zero cable length) using low-inductance adapters, or installed directly on the end of a AV-HLZ1-100 cable plugged into the output connector. Inductive loads or cables will degrade the rise and fall times. 37 Lower load resistances may also degrade the rise and fall times proportionally (since the inductive time constant is given by τ = L / R). That is, if the load impedance is reduced by a factor of 10, to 0.1 Ohms, the observed rise time may increase by a factor of ten. 38 CURRENT MONITOR A current monitor output is provided on the rear panel of the instrument. The voltage waveform of the monitor output is proportional to the current waveform on the main output: VMON = IOUT × 1V/10A for a load of > 1 kΩ. (The monitor output can also drive a 50Ω load, but the output voltage will be reduced by a factor of 2. This output is short-circuit protected.) The current monitor circuit also measures the amplitude of the most recent pulse, in amperes, and displays it on the front panel LCD. The value can also be read via the computer interface. The monitor loses accuracy for pulse widths of 10 us and less. The voltage output is not sufficiently fast or accurate for measuring current rise and fall times. The output during the first 10 us of the rise or fall time may display “spikes”, which are measurement artifacts, and are not true measurements. ALARMS The AVO-8A3-B-P has several protective circuits. An alarm circuit, with an audible buzzer, will sound and disable the output if: 1) The DC power supply voltage exceeds 59V. 2) The output circuitry overheats. 3) The maximum output current (60A) is exceeded. The buzzer may sound briefly when the power is first switched on. This is normal, and not a cause for concern. 39 -TRIP OPTION (ADJUSTABLE CURRENT LIMIT) Instruments with the -TRIP option allow a current-limit to be set in the range of 10A to 60A. If the output current exceeds this programmed limit, the output will be disabled within 5 us. The limit is accurate to ± 2% ± 1 Amp. This option is intended as a safety feature. It is still important to select the series resistance such that excessive currents will not normally occur. The trip level may be set from the front panel “LIM” menu, or by a software command. For example: source:current:limit:amplitude 25A This can be shortened to: curr:lim 25A if desired. 40 START-UP CHECK-LIST FOR LOCAL CONTROL 1) Read this manual thoroughly. 2) Read the “Local Control” section of the “Programming Manual for -B Instruments” thoroughly. 3) Connect the load to the output module. Note that with a diode load, a lowinductance current limiting high power resistor must be placed in series with the diode to help limit the peak current. For initial testing, it is recommended that a resistive load be used. Factory tests are conducted using a 1.0 Ohm 4000 Watt water-cooled resistive load (the Avtech AV-HTL-1R0-HLZ, see http://www.avtechpulse.com/accessories/av-htl-1r0 for details). 4) Connect the DC power supply to the instrument, as shown in the "Connecting to a Power Supply" section. 5) Turn on the prime power to the mainframe. The main menu will appear. 6) The arrow pointer should be pointing at the frequency menu item. If it is not, press the MOVE button until it is. 7) Press the CHANGE button. The frequency submenu will appear. Rotate the ADJUST knob until the frequency is set at the desired setting. The arrow pointer should be pointing at the “Internal” choice. If it is not, press MOVE until it is. 8) Press CHANGE to return to the main menu. 9) Press the MOVE button to move the arrow pointer to the pulse width menu item. Press CHANGE to bring up the pulse width submenu, and rotate the ADJUST knob until the pulse width is set at the desired setting. The arrow pointer should be pointing at the “Normal” choice. If it is not, press MOVE until it is. Press CHANGE to return to the main menu. 10) Press the MOVE button to move the arrow pointer to the pulse width menu item. Press CHANGE to bring up the pulse width submenu, and rotate the ADJUST knob until the pulse width is set at the desired setting. The arrow pointer should be pointing at the “Normal” choice. If it is not, press MOVE until it is. Press CHANGE to return to the main menu. 11) Press the MOVE button to move the arrow pointer is pointing at the output item. Press CHANGE to bring up the output submenu. The arrow pointer should be initially be pointing at the “Output Off” choice. Press MOVE so that the arrow pointer is pointing at the “Output On” choice. (The mainframe is now supplying a trigger to the output module.) Press CHANGE to return to the main menu. 41 12) Connect a scope probe across the resistive test load and apply prime power to the lab power supply (after first ensuring that the output amplitude is set to zero). 13) Gradually increase the output amplitude on the lab power supply and observe the waveforms on the scope and the DC current level on the DC power supply. A rectangular pulse should appear on the scope (for both the load voltage and monitor channels) and the amplitude should increase as the amplitude control on the mainframe is rotated clockwise. At the same time, the average current supplied by the DC supply will increase. 14) Observe the pulse width and pulse period on the scope and confirm that the peak current does not exceed 50 Amps. 15) Observe the DC current supplied by the DC supply and ensure that the average current does not exceed 50 Amperes. 16) Adjust pulse width, pulse period (i.e. PRF) and amplitude to obtain the desired settings. 42 PROGRAMMING YOUR PULSE GENERATOR KEY PROGRAMMING COMMANDS The “Programming Manual for -B Instruments” describes in detail how to connect the pulse generator to your computer, and the programming commands themselves. A large number of commands are available; however, normally you will only need a few of these. Here is a basic sample sequence of commands that might be sent to the instrument after power-up: *rst trigger:source internal source:function pulse frequency 100 Hz pulse:width 100 us pulse:delay 30 us curr:lim 45A output on (resets the instrument) (selects internal triggering) (enables pulse mode, rather than DC mode) (sets the frequency to 100 Hz) (sets the pulse width to 100 us) (sets the delay to 30 us) (sets current limit at 45A, for units with -TRIP option) (turns on the output) These commands will satisfy 90% of your programming needs. ALL PROGRAMMING COMMANDS For more advanced programmers, a complete list of the available commands is given below. These commands are described in detail in the “Programming Manual for -B Instruments”. (Note: this manual also includes some commands that are not implemented in this instrument. They can be ignored.) Keyword LOCAL OUTPut: :[STATe] :PROTection :TRIPped?

With the four screws removed, the top cover may be slid back (and off). Always disconnect the power cord and allow the instrument to sit unpowered for 10 minutes before opening the instrument. This will allow any internal stored charge to discharge. There are no user-adjustable internal circuits. For repairs other than fuse replacement, please contact Avtech ([email protected]) to arrange for the instrument to be returned to the factory for repair. Service is to be performed solely by qualified service personnel. Caution: High voltages are present inside the instrument during normal operation. Do not operate the instrument with the cover removed. RACK MOUNTING A rack mounting kit is available. The -R6 rack mount kit may be installed after first removing the one Phillips screw on the side panel adjacent to the front handle. ELECTROMAGNETIC INTERFERENCE To prevent electromagnetic interference with other equipment, all used outputs should be connected to shielded loads using shielded coaxial cables. Unused outputs should be terminated with shielded coaxial terminators or with shielded coaxial dust caps, to prevent unintentional electromagnetic radiation. All cords and cables should be less than 3m in length. 45 MAINTENANCE REGULAR MAINTENANCE This instrument does not require any regular maintenance. On occasion, one or more of the four rear-panel fuses may require replacement. All fuses can be accessed from the rear panel. See the “FUSES” section for details. CLEANING If desired, the interior of the instrument may be cleaned using compressed air to dislodge any accumulated dust. (See the “TOP COVER REMOVAL” section for instructions on accessing the interior.) No other cleaning is recommended.
