5 INTRODUCTION The AVR-G1-B-P-EMRA-R5-RP-IM is a customized high performance, GPIB and RS232-equipped instrument capable of generating up to +240V at repetition rates up to 10 kHz into resistive loads of 1.6 kΩ or higher, with a capacitance of up to 900 pF. The pulse width is variable from 3 us to 30 us, and the duty cycle may be as high as 30%. The rise time is < 10 ns into a resistive load, and the fall time is < 20 ns. This instrument includes a current monitor. The monitor circuit samples the output current at the end of the pulse, and reports it on the front panel LCD. The value may also be queried remotely using the “meas:ampl?” command. The current monitor circuit also provides a rear-panel “M” BNC connector. The voltage waveform on this connector is proportional to the output current (V M = IOUT x 2V / 100 mA), for currents of up to 250 mA. The voltage waveform is pulsed, similar to the main output. It is not a DC output. The AVR-G1-B-P-EMRA-R5-RP-IM includes an internal trigger source, but it can also be triggered or gated by an external source. A front-panel pushbutton can also be used to trigger the instrument. The output pulse width can be set to follow an input trigger pulse width. The AVR-G1-B-P-EMRA-R5-RP-IM features front panel keyboard and adjust knob control of the output pulse parameters along with a four line by 40-character backlit LCD display of the output amplitude, pulse width, pulse repetition frequency, and delay. 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. The instrument is protected against overload conditions (such as short circuits) by an automatic control circuit. An internal power supply monitor removes the power to the output stage for five seconds if an average power overload exists. After that time, the unit operates normally for one second, and if the overload condition persists, the power is cut again. This cycle repeats until the overload is removed. This instrument is intended for use in research, development, test and calibration laboratories by qualified personnel. INCLUDED OPTIONS -R5 Option: Rack-mount kit. -RP Option: The output is on the rear panel, instead of on the front panel. -IM Option: Provides a digital current monitor circuit, as well as an analog current monitor waveform (VM = IOUT x 2V / 100 mA).

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

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 60 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, or the instrument may remain unresponsive indefinitely. 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. 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.
16 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. 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.

Note: some connectors may be in different positions than shown above, depending on the exact combination of options ordered. 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.)
18 When triggering externally, the instrument can be set such that the output pulse width tracks the pulse width on this input, or the output pulse width can be set independently. 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. A user name (“admin”) and a password (“default”, as shipped from the factory) are required when logging into a serial terminal session. The internal controller attempts to autosense the parity setting. It may be necessary to send a few return characters before attempting a login in order to provide enough data to allow this auto-sensing to work. (A standard Linux “agetty” process is used to implement serial control internally.) See the “Programming Manual for -B Instruments” for more details on RS-232 control. 8. OUT CONNECTOR. This connector provides the output to a 1.6 kΩ (or higher) load, with a load capacitance of 900 pF or less. Caution: Voltages as high as +240V 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. 9. AMP Connector. The voltage waveform on this connector is proportional to the output current (VM = IOUT x 2V / 100 mA), for currents of up to 250 mA. The voltage waveform is pulsed, similar to the main output. It is not a DC output. This output is intended to drive high impedance (> 10 kΩ) loads, such as an oscilloscope probe. It can drive 50Ω loads, but the output voltage will be reduced by a factor of two, approximately. The output accuracy is ± 10%. The DC component of the waveform varies as a function of duty cycle and other parameters, and should be ignored. The pulse amplitude (peakto-peak) should be measured instead.
19 GENERAL INFORMATION 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 a positive delay:

DELAY > 0

Figure C 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
AMPLITUDE, VARIABLE
MAIN OUTPUT
Figure D The delay, pulse width, and frequency (when in the internal mode), of the OUT pulse can be varied with front panel controls or via the GPIB or RS-232 computer interfaces.
21 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.
22 OUTPUT IMPEDANCE The AVR-G1-B-P-EMRA-R5-RP-IM has an output impedance (i.e., an internal resistance in series with the output) of 50 Ohms, to provide transmission line backmatching and short-circuit protection. If the load is capacitive, the RC time constant of the output impedance and the capacitive load will tend to degrade the rise and fall times. CURRENT MONITOR This instrument includes a current monitor, for measuring output currents of up to 250 mA. The monitor circuit samples the output current at the end of the pulse, and reports it on the front panel LCD. The value may also be queried remotely using the “meas:ampl?” command. The current monitor circuit also provides a rear-panel “M” BNC connector. The voltage waveform on this connector is proportional to the output current (VM = IOUT x 2V / 100 mA), for currents of up to 250 mA. The voltage waveform is pulsed, similar to the main output. It is not a DC output. This output is intended to drive high impedance (> 10 kΩ) loads, such as an oscilloscope probe. It can drive 50Ω loads, but the output voltage will be reduced by a factor of two, approximately. The DC component of the waveform varies as a function of duty cycle and other parameters, and should be ignored. The pulse amplitude (peak-topeak) should be measured instead. PREVENTING OUTPUT STAGE FAILURE The output stage is protected against overload conditions by an overload circuit and fuses on the main frame back panel. However, the output switching elements may fail if the unit is triggered at a PRF exceeding 10 kHz or at duty cycles resulting in an average output power in excess of 11 Watts. Heating and subsequent possible failure of the output stage is reduced if the following action is taken where possible:
PRF is kept to a minimum, i.e. operate in a low PRF range when possible rather than in a high PRF range.
Keep the output pulse width to a minimum.
Never apply an externally generated voltage to the output port.
23 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 read 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.

TRIG INPUT
ALL CABLES: 50 OHM COAXIAL
1. Connect a cable from the SYNC OUT connector to the TRIG input of an oscilloscope. Connect a 11W (or higher) 1.6 kΩ load to the OUT connector and place the scope probe across this load. The load resistor must have a voltage rating of at least 240V. The power dissipated in the resistor is given by P = (V2 / R) × (PW / T) = (V2 / R) × PW × f where “V” is the output voltage, “R” is the load resistance, “PW” is the pulse width, and “T” is the pulse period (1/frequency), and “f” is the frequency. 2. Set the oscilloscope to trigger externally with the vertical setting at 50 Volts/div and the horizontal setting at 1 us/div. Be sure that your oscilloscope and probe setup can handle the maximum amplitude of 240V. The load resistor should be rated for at least 240V of voltage and 20W of power. 3. Turn on the AVR-G1-B-P-EMRA-R5-RP-IM. The main menu will appear on the LCD.
24 4. To set the AVR-G1-B-P-EMRA-R5-RP-IM to trigger from the internal clock at a PRF of 1 kHz: The arrow pointer should be pointing at the frequency menu item. If it is not, press the MOVE button until it is. Press the CHANGE button. The frequency submenu will appear. Rotate the ADJUST knob until the frequency is set at 1 kHz. The arrow pointer should be pointing at the “Internal” choice. If it is not, press MOVE until it is. Press CHANGE to return to the main menu. 5. To set the delay to 1 us: Press the MOVE button until the arrow pointer is pointing at the delay menu item. Press the CHANGE button. The delay submenu will appear. Rotate the ADJUST knob until the delay is set at 1 us. 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. 6. To set the pulse width to 5 us: Press the MOVE button until the arrow pointer is pointing at the pulse width menu item. Press the CHANGE button. The pulse width submenu will appear. Rotate the ADJUST knob until the pulse width is set at 5 us. 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. 7. At this point, nothing should appear on the oscilloscope. 8. To enable the output: Press the MOVE button until the arrow pointer is pointing at the output menu item.
25 Press the CHANGE button. The output submenu will appear. Press MOVE until the arrow pointer is pointing at the “ON” choice. Press CHANGE to return to the main menu. 9. To change the output amplitude: Press the MOVE button until the arrow pointer is pointing at the amplitude menu item. Press the CHANGE button. The amplitude submenu will appear. Rotate the ADJUST knob until the amplitude is set at +240V. Observe the oscilloscope. You should see 5 us wide, 240V pulses. Rotate the ADJUST knob. The amplitude as seen on the oscilloscope should vary. Press CHANGE to return to the main menu. 10. Repeat step 9, but set the amplitude to zero. 11. This completes the operational check.
26 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 frequency 1000 Hz pulse:width 5 us pulse:delay 2 us volt 240 output on measure:amplitude?
(resets the instrument) (selects internal triggering) (sets the frequency to 1000 Hz) (sets the pulse width to 5 us) (sets the delay to 2 us) (sets the amplitude to 240 V) (turns on the output) (this returns the peak current, in amperes, as measured by the monitor circuit)
For triggering a single event, this sequence would be more appropriate: *rst trigger:source hold pulse:width 5 us pulse:delay 2 us output on volt 240 trigger:source immediate trigger:source hold measure:amplitude? output off
(resets the instrument) (turns off all triggering) (sets the pulse width to 5 us) (sets the delay to 2 us) (turns on the output) (sets the amplitude to 240 V) (generates a single non-repetitive trigger event) (turns off all triggering) (this returns the peak current, in amperes, as measured by the monitor circuit) (turns off the output)
To set the instrument to trigger from an external TTL signal applied to the rear-panel TRIG connector, use: *rst trigger:source external pulse:width 5 us pulse:delay 2 us volt 240 output on measure:amplitude?
(resets the instrument) (selects internal triggering) (sets the pulse width to 5 us) (sets the delay to 2 us) (sets the amplitude to 240 V) (turns on the output) (this returns the peak current, in amperes, as measured by the monitor circuit)
27 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 MEASure: :AMPLitude? OUTPut: :[STATe] :PROTection :TRIPped?

29 MECHANICAL INFORMATION TOP COVER REMOVAL If necessary, the interior of the instrument may be accessed by removing the four Phillips screws on the top panel. 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.
30 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.
