Copyright © 2013 Avtech Electrosystems Ltd, All Rights Reserved. 5 INTRODUCTION The AV-151C-B is a high-performance GPIB and RS232-equipped function generator that can produce square, sine, triangle, and pulse outputs with peak amplitudes of up to 100V. For the sine, triangle, and square wave modes, this produces peak-to-peak amplitudes of up to 200V. The AV-151C-B will drive load impedances of 10 kΩ or higher. When supplied with an external voltage input, the AV-151C-B may be used as a DC to 200 kHz variable-gain linear amplifier. The gain is variable up to +50. The maximum operating frequency and -3 dB bandwidth is 200 kHz. The AV-151C-B features front panel keyboard and adjust knob control of the output pulse parameters along with a four line by 40 character back-lit LCD display of the output amplitude, wave shape, and frequency. The instrument includes memory to store up to four complete instrument setups. The operator may use the front panel or the computer interface to store a complete “snapshot” of all key instrument settings, and recall this setup at a later time. This instrument is intended for use in research, development, test and calibration laboratories by qualified personnel. 6 SPECIFICATIONS Model1: AV-151C-B 2 Maximum amplitude & maximum peak output3: ± 100 V Load resistance: ≥ 10 kΩ Min. Frequency: 1 Hz Max. frequency (int mode), -3dB bandwidth (ext mode) Waveforms: 200 kHz Sine, square, triangle,pulse. (The pulse mode is positive only.) 5 Pulse width (FWHM) : 2 us – 0.5s Maximum DC offset: ± 25V6 Square wave rise time (20%80%)7: 0.8 us Ext trig mode: Burst mode: GPIB / RS-232 control1: Ethernet port, for remote control using VXI-11.3, ssh, telnet, & web: LabView drivers: Input for maximum output: ± 2 Volts. (1 kΩ input impedance) Optional7. This allows the generation of a burst of 1-500 cycles of sine, square, triangle, or pulse waveforms. This burst may be triggered by pressing a front-panel pushbutton, or by computer command. Standard on -B units. Optional8. Recommended as a modern alternative to GPIB / RS-232. See http://www.avtechpulse.com/options/vxi for details. Available for download at http://www.avtechpulse.com/labview. Settings resolution: The resolution of the timing parameters varies, but is always better than 0.15% of the set value. The amplitude and offset resolution is typically 0.02% of the maximum amplitude. Settings accuracy: Typically ± 3% after 10 minute warmup. For high-accuracy applications requiring traceable calibration, verify the output parameters with a calibrated oscilloscope. Connectors: Power requirement: Operating temperature: Dimensions: BNC 100 - 240 Volts, 50 - 60 Hz +5°C to +40°C 100 x 430 x 375 mm (3.9” x 17” x 14.8”) The -B suffix indicates IEEE-488.2 GPIB and RS-232 control of amplitude and frequency. See http://www.avtechpulse.com/gpib/ for details. The minimum useful amplitude is 5% of the maximum amplitude. Peak output = amplitude + offset. The amplitude and offset can not be set to maximum at the same time, or the peak output rating will be exceeded. The output current will be largely independent of the load voltage, but the load voltage must stay within this range for proper operation. Subject to a maximum duty cycle limit of 80%. The maximum offset may be increased to equal the “maximum peak output” rating by adding the suffix “-XOS” to the model number. Valid into a resistive load installed directly on the output connector. Long lengths of cabling may degrade rise times. N on-zero rise times will noticeably distort the sine and triangle waveforms when operating near the maximum rated frequency. 8) Add the suffix -VXI to the model number to specify the Ethernet port. 9) Add the suffix -PANB to the model number to specify the burst mode option. 1) 2) 3) 4) 5) 6) 7) 7 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. Contact Avtech ([email protected]) if you require assistance. EC DECLARATION OF CONFORMITY We Avtech Electrosystems Ltd. P.O.

According to the manufacturer, the Tamura AAD130SD-60-A has the following certifications: UL60950-1 IEC60950 -1 CSA C22.2 No. 60950- 1 EN60950 -1 and is compliant with: EN61000-3-2 EN61000-4-2 Level 2 EN61000-4-2 Level 3 (Air Only) EN61000-4-4 Level 3 EN61000-4-5 Level 3 EN61000-4-11 CISPR 11 and 22 FCC Part 15 Class B (conducted) FIRMWARE LICENSING Instruments with firmware versions 5.00 or higher use open-source software internally. Some of this software requires that the source code be made available to the user as a condition of its licensing. This source code is distributed on the device itself. To access it, log in as user “source” with password “source”. The source files are provided in this user's home directory, and are accessible using standard viewing and file transfer tools (such as vim, sz, and scp). Earlier firmware versions do not contain any open source software. 10 INSTALLATION VISUAL CHECK After unpacking the instrument, examine to ensure that it has not been damaged in shipment. Visually inspect all connectors, knobs, liquid crystal displays (LCDs), and the handles. Confirm that a power cord, a GPIB cable, and two instrumentation manuals (this manual and the “Programming Manual for -B Instruments”) are with the instrument. If the instrument has been damaged, file a claim immediately with the company that transported the instrument. POWER RATINGS This instrument is intended to operate from 100 - 240 V, 50 - 60 Hz. The maximum power consumption is 57 Watts. Please see the “FUSES” section for information about the appropriate AC and DC fuses. This instrument is an “Installation Category II” instrument, intended for operation from a normal single-phase supply. CONNECTION TO THE POWER SUPPLY An IEC-320 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. The other end of the detachable power cord plugs into the local mains supply. Use only the cable supplied with the instrument. The mains supply must be earthed, and the cord used to connect the instrument to the mains supply must provide an earth connection. (The supplied cord does this.) Warning: Failure to use a grounded outlet may result in injury or death due to electric shock. This product uses a power cord with a ground connection. It must be connected to a properly grounded outlet. The instrument chassis is connected to the ground wire in the power cord. The table below describes the power cord that is normally supplied with this instrument, depending on the destination region: 11 Destination Region Description Option Manufacturer Part Number United Kingdom, Hong Kong, Singapore, Malaysia BS 1363, 230V, 50 Hz -AC00 Qualtek 370001-E01 Australia, New Zealand AS 3112:2000, 230-240V, 50 Hz -AC01 Qualtek 374003-A01 Continental Europe, Korea, Indonesia, Russia European CEE 7/7 “Schuko” 230V, 50 Hz -AC02 Qualtek 364002-D01 North America, Taiwan NEMA 5-15, 120V, 60 Hz -AC03 Qualtek 312007-01 Switzerland SEV 1011, 230V, 50 Hz -AC06 Qualtek 378001-E01 South Africa, India SABS 164-1, 220-250V, 50 Hz -AC17 Volex 2131H 10 C3 Japan JIS 8303, 100V, 50-60 Hz -AC18 Qualtek 397002-01 Israel SI 32, 220V, 50 Hz -AC19 Qualtek 398001-01 China GB 1002-1, 220V, 50 Hz -AC22 Volex 2137H 10 C3 PROTECTION FROM ELECTRIC SHOCK Operators of this instrument must be protected from electric shock at all times. 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. 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. 12 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. LABVIEW DRIVERS A LabVIEW driver for this instrument is available for download on the Avtech web site, at http://www.avtechpulse.com/labview. A copy is also available in National Instruments' Instrument Driver Library at http://www.natinst.com/. 13 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 14 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 0.8A, 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 5×20 mm 0218.800HXP F2418-ND 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. 15 FRONT PANEL CONTROLS 1 2 3 6 5 4 1. POWER Switch. This is the main power switch. When turning the instrument on, there is normally a delay of 5-10 seconds before anything is shown on the main display. If the main menu does not appear after 30 seconds, turn off the instrument and leave it off for at least 60 seconds before applying power again. Allow 30 seconds before re-powering an instrument that has been switched off. If the power is switched more frequently than that, the turn-on delay may be longer (up to 20 seconds) as the internal software performs filesystem checks. 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. OUT Connector. This BNC connector provides the main output signal, into load impedances of > 10 kΩ. Caution: Voltages as high as ±100V may be present on the center conductor of this output connector. Avoid touching this conductor. Connect to this connector using standard coaxial cable, to ensure that the center conductor is not exposed. 16 4. SYNC OUT. This connector supplies a SYNC output that can be used to trigger other equipment, particularly oscilloscopes. This signal has an approximate amplitude of +3 Volts to RL > 1 kΩ with a pulse width of approximately 100 ns. 5. 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. 6. 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. 17 REAR PANEL CONTROLS 4 5 8 1 3 GATE TRIG RS-232 AMP GPIB 9 6 7 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. Not used. 5. TRIG. When the AV-151C-B is set to operate in the amplifier mode, the externallygenerated input signal is applied to this connector. The maximum input voltage is ±2V. 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.) 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. Instruments with firmware versions of 5.00 or higher require a user name (“admin”) and a password (“default”, as shipped from the factory) when logging into a serial terminal session. See the “Programming Manual for -B Instruments” for more details 18 on RS-232 control. 8. Network Connector. (Optional feature. Present on -VXI units only.) This Ethernet connector allows the instrument to be remotely controlled using the VXI-11.3, ssh (secure shell), telnet, and http (web) protocols. See the “Programming Manual for -B Instruments” for more details. 9. AMP Connector. Not used. 19 GENERAL INFORMATION WAVESHAPE SELECTION The front-panel “SHAPE” menu or the “sour:func” computer command can be used to set the output waveform to one of five possible modes: SINE – This mode generates a bipolar sinusoidal signal with 50% duty cycle. TRIANGLE – This mode generates a bipolar triangle-wave signal with 50% duty cycle. SQUARE – This mode generates a bipolar square-wave signal with 50% duty cycle. PULSE – This mode generates a unipolar pulse signal, with adjustable pulse width. AMPLIFY – This mode causes the instrument to amplify an externally-generated signal. SINE, TRIANGLE, AND SQUARE WAVE GENERATION When set to the SINE, TRIANGLE, or SQUARE modes, the output frequency and peak amplitude are controlled from the front panel (or by computer command). The output signal is these modes is bipolar (i.e., the signal swings from a positive value to an approximately equal negative amplitude), and the duty cycle is nominally 50% (i.e., time that the signal is positive is equal in length to the time that the signal is negative.) These waveforms are illustrated below: Sine Peak voltage: 0 to 100V Triangle Square A DC offset in the range of ±25V (or ±100V for units with the -XOS option) may also be added: 20 DC Offset, 0 to ±25V (0 to ±100V for -XOS units) ZERO VOLTS The total output (i.e., the sum of the offset and the amplitude) may not exceed ±100V. A SYNC output is provided on the front-panel. This provides a 100 ns, 3V signal for triggering oscilloscopes or other equipment. In these modes, the delay (or relative phase) between the main output and the SYNC output is not adjustable. PULSE GENERATION The AV-151C-B can also act as a pulse generator, with variable delay between the SYNC output and the main output. In this mode, the pulse width may be varied over a wide range (1 us to 500 ms), and the amplitude may be varied from 0 to +100V. (Negative pulses can not be generated directly. However, they can be generated indirectly by adding a negative DC offset. See the offset discussion below.) The maximum duty cycle (100% x Pulse Width / Period) is 80%. The outputs in this mode are shown below, assuming that the delay is set to a positive value: SYNC OUT (generated by the internal oscillator) 100 ns, FIXED 3V, FIXED DELAY > 0 MAIN OUTPUT PULSE WIDTH AMPLITUDE, VARIABLE If the delay is negative, the order of the SYNC and OUT pulses is reversed: 21 100 ns, FIXED SYNC OUT (generated by the internal oscillator) 3V, FIXED DELAY < 0 PULSE WIDTH MAIN OUTPUT AMPLITUDE, VARIABLE AMPLIFY MODE When the AMPLIFY mode is enabled, AV-151C-B may be used as a DC - 200 kHz variable-gain linear amplifier. The maximum gain is +50. The maximum input signal is ±2V. The gain is adjusted by varying the amplitude setting, which corresponds to the output that would be obtained for a +2V input. (For instance, to obtain a gain of +15, set the amplitude to +30V. If a -0.8V signal is applied, for instance, the actual output would be -12V, not +30V.) The required voltage input signal is applied at TRIG for this mode of operation. This mode is illustrated below: INPUT VOLTAGE, ON "IN" CONNECTOR OUTPUT VOLTAGE, ON "OUT" CONNECTOR ARBITRARY WAVEFORM, VIN, ± 2V MAXIMUM VOUT = VIN × GAIN, GAIN = UP TO +50, ADJUSTABLE. ± 100V MAXIMUM. CABLE LENGTHS (KEEP THEM SHORT) The length of cable used to connect the load to the output of the function generator should be less than 3 feet (1 meter), and ideally less than 18 inches (0.5 meters). At longer lengths, the transmission line reflections caused by the cabling will distort the output signal, particularly if the “square” waveform mode is used. If this is problematic, 22 it may be possible to reduce the distortions by adding a series resistance between the front-panel output connector and the cable. The RC time constant of this resistance and the cable capacitance will act as a passive filter which may remove some distortion, at the expense of slower rise and fall times. Resistances in the range of 100 to 1000 Ohms may be appropriate for this application. SHORT CIRCUITS The output stage is protected against short-circuits. The maximum output current will be limited to approximately 40 mA under short-circuit conditions. Short circuit conditions should not be allowed to persist for more than a few minutes, or the resulting thermal stresses may shorten the lifetime of the output stage. CAPACITIVE LOADS The AV-151C-B can drive capacitive loads of up to 1000 pF, but the maximum “slew rate” (dV/dt) will be limited by the charging capability of the output stage. In other words, the rise time and the maximum operating frequency will degrade. As noted above, the output current is limited by protective circuits to approximately 40 mA (I MAX). The maximum slew rate that can be obtained into a capacitance “C” is then given by: IMAX = C × dV/dt so dV / dt = (40 mA) / C approximately. 23 -PANB BURST MODE OPTION The -PANB option allows the generation of a burst of 1-500 cycles of sine, square, triangle, or pulse waveforms. This burst may be triggered by pressing a front-panel pushbutton, or by computer command. Beware that the instrument generates a burst output every time the pulse count (N) is changed (e.g., when the pulse:count command is sent, or when the pulse count is adjusted from the front panel). LOCAL MODE The number of waveform cycle in each burst can be controlled from the front panel. The display normally shows “N=xxx” (xxx may range from 0 to 500), where N is the number of cycles in each burst. When N=0, the instrument generates the output signal continuously – that is, the burst mode is disabled. When N>0, the instrument is in burst mode. A burst may be triggered by pressing the “SINGLE PULSE” pushbutton. A burst is also triggered any time that the value of the pulse count (N) is changed. For instance, when the ADJUST knob is rotated when the pulse count menu is displayed, a burst will be generated each time N increments or decrements. If this triggering is undesirable, set the amplitude to zero before adjusting the pulse count, and return the amplitude to the desired value after the pulse count is set properly. REMOTE MODE When controlling the instrument from the GPIB or RS-232 ports, the burst mode is controlled using the “pulse:count” command. Sending “pulse:count 0” disables the burst mode. That is, the instrument generates the output signal continuously. Sending “pulse:count xxx”, where xxx is a number between 1 and 500, triggers a burst with xxx cycles of the output waveform. The front-panel “SINGLE PULSE” pushbutton remains active in the remote mode. Pressing the “SINGLE PULSE” pushbutton after a “pulse:count” command will generate a burst, using the most recent pulse count setting. 24 SYNC OUTPUT In non-bursted operation, a 100 ns wide SYNC pulse is generated for each waveform cycle. This behaviour changes for burst mode operation. In this mode, a single SYNC pulse is generated for each burst, rather than each waveform cycle. The SYNC pulse width is equal to the duration of the burst. This simplifies the triggering of oscilloscopes. The delay feature is disabled for pulse waveforms in the burst mode. 25 OPERATIONAL CHECK This section describes a sequence to confirm the basic operation of the instrument. It should be performed after receiving the instrument. It is a useful learning exercise as well. Before proceeding with this procedure, finish reading this instruction manual thoroughly. Then read the “Local Control” section of the “Programming Manual for -B Instruments” thoroughly. The “Local Control” section describes the front panel controls used in this operational check - in particular, the MOVE, CHANGE, and ADJUST controls. REAL-TIME OSCILLOSCOPE AVTECH AV-151C-B MAIN OUTPUT CONNECTOR SCOPE PROBE CHANNEL A TEST LOAD, 10 kΩ AC POWER TRIG INPUT SYNC OUTPUT Basic Test Arrangement 1. Connect a 10 kΩ test load between the OUT connector and ground. (Confirm that the oscilloscope and the test load are rated for 100 Volt operation.) The photo below shows how factory tests are conducted, using a 10 kΩ, 2 W resistor (Ohmite OY series) installed across a Pomona 1296 BNC-to-binding-post adapter. 26 2. Connect a cable from the SYNC connector to the TRIG input of an oscilloscope. Set the oscilloscope to trigger externally. 3. Connect an oscilloscope probe to the load. On the oscilloscope, set the vertical scale to 50 V/div, and the horizontal scale to 20 us/div. 4. Turn on the AV-151C-B. The main menu will appear on the LCD. 5. To set the AV-151C-B to trigger from the internal clock at a PRF of 30 kHz: a) The arrow pointer should be pointing at the frequency menu item. If it is not, press the MOVE button until it is. b) Press the CHANGE button. The frequency submenu will appear. Rotate the ADJUST knob until the frequency is set at 30 kHz. c) Press CHANGE to return to the main menu. 6. To set the waveshape to a sinusoid: a) Press the MOVE button until the arrow pointer is pointing at the shape menu item. b) Press the CHANGE button. The delay submenu will appear. c) Press MOVE until the arrow pointer is pointing at the “SINE” choice. 27 d) Press CHANGE to return to the main menu. 7. At this point, nothing should appear on the oscilloscope. 8. To enable the output: a) Press the MOVE button until the arrow pointer is pointing at the output menu item. b) Press the CHANGE button. The output submenu will appear. c) Press MOVE until the arrow pointer is pointing at the “ON” choice. d) Press CHANGE to return to the main menu. 9. To change the output amplitude: a) Press the MOVE button until the arrow pointer is pointing at the amplitude menu item. b) Press the CHANGE button. The amplitude submenu will appear. Rotate the ADJUST knob until the amplitude is set at +100V. c) Observe the oscilloscope. You should see a 30 kHz, 100V peak (200V peak-topeak) sine wave. d) Press CHANGE to return to the main menu. This completes the operational check. 28 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, using the internal trigger source: *rst sour:func sin frequency 1000 Hz output on volt 100 volt:low -10 (resets the instrument) (selects a sine wave output) (sets the frequency to 1000 Hz) (turns on the output) (sets the amplitude to 100 V) (sets the offset to -10 V) To generate a pulse output, use: *rst sour:func pulse frequency 1000 Hz pulse:width 10 us pulse:delay 1 us output on volt 100 volt:low -10 (resets the instrument) (selects a unipolar pulse output) (sets the frequency to 1000 Hz) (sets the pulse width to 10 us) (sets the delay to 1 us) (turns on the output) (sets the amplitude to 100 V) (sets the offset to -10 V) To amplify an external signal, use: *rst sour:func amp output on volt 100 volt:low -10 (resets the instrument) (enables the amplifier mode) (turns on the output) (sets the gain to 100 / 2 = 50) (sets the offset to -10 V) These commands will satisfy 90% of your programming needs. 29 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 -R5 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. 32 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. 33 OTHER INFORMATION APPLICATION NOTES Application notes are available on the Avtech web site, at http://www.avtechpulse.com/appnote.
