The pulse width is variable from 200 ns to 500 ms, and the duty cycle may be as high as 80%. Rise and fall times are fixed at less than 40 ns. The AVR-GHV1-B 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 output voltage polarity depends on the model number: "-P" units: 0 to +500 Volts "-N" units: 0 to -500 Volts "-PN" units: 0 to ±500 Volts The AVR-GHV1-B 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. 6 AVAILABLE OPTIONS -BR Option: This optional feature allows a burst of 1-500 pulses to be generated in response to each trigger event. -HN Option: The standard N-type output connector is replaced with an HN-type connector. -MHV Option: The standard N-type output connector is replaced with an MHV-type connector. -SHV Option: The standard N-type output connector is replaced with an SHV-type connector. -R5 Option: Rack-mount kit. -TNT Option: Adds a rear-panel Ethernet connector, providing Telnet-based remote control from a network. 7 HIGH-VOLTAGE PRECAUTIONS CAUTION: This instrument provides output voltages as high as 500 Volts under normal operating conditions, and generates up to 530V internally, so extreme caution must be employed when using this instrument. The instrument should only be used by individuals who are thoroughly skilled in high voltage laboratory techniques. The following precautions should always be observed: 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. 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. 8 SPECIFICATIONS Model: AVR-GHV1-B1 Amplitude: 0 to 500 Volts Pulse width (FWHM) : 2 Load impedance: 200 ns to 0.5 sec ≥ 100 kΩ Output impedance: 50 Ω (i.e., internal resistance in series with the output). 7 Rise time (20%-80%) : ≤ 40 ns Fall time (80%-20%) : ≤ 40 ns 7 PRF: Duty cycle: Polarity3: GPIB and RS-232 control1: LabView Drivers: Telnet / Ethernet control4: Burst mode: 1 Hz to 1 kHz 0 - 80 % Positive or negative or both (specify) Standard on -B units Check http://www.avtechpulse.com/labview for availability and downloads Optional on -B units.

Type N BNC 100 - 240 Volts, 50 - 60 Hz 100 mm x 430 mm x 375 mm (3.9” x 17” x 14.8”) Chassis material: cast aluminum frame and handles, blue vinyl on aluminum cover plates Mounting: Any. Add the suffix -R5 to the model number to include a rack-mount kit. Temperature range: +5°C to +40°C 1) -B suffix indicates IEEE-488.2 GPIB and RS-232 control of amplitude, pulse width or duty cycle (as appropriate), pulse repetition frequency, and delay (See http://www.avtechpulse.com/gpib). 2) When triggered externally, the pulse width can be set by the pulse instrument controls, or it may be set to track the input trigger pulse width. 3) Indicate desired polarity by suffixing model number with -P or -N (i.e. positive or negative) or -PN for dual polarity option (controlled by a two-position switch which controls the polarity of the signal output port). Keypad polarity control on -B units. 4) Add the suffix -TNT to the model number to specify the Telnet / Ethernet control option. 5) Add the suffix -BR to the model number to specify the burst mode option. See http://www.avtechpulse.com/options/br for details about this option. 6) HV, MHV or HN output connectors can also be provided. To specify, suffix the model number by -SHV, -MHV or -HN as required. 7) Valid when the load is connected with zero cable length (for instance, on a binding post adapter). The rise and fall times will degrade for non-zero lengths of cable, due to the product of the 50 Ohm output impedance and the cable capacitance. The maximum cable length for operation (with degraded rise and fall times) is 2 meters (6 feet). If your application requires longer cable lengths, contact Avtech for appropriate modifications or applications assistance. 9 EUROPEAN REGULATORY NOTES EC DECLARATION OF CONFORMITY We Avtech Electrosystems Ltd.

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/. 14 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 15 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 0.5A, 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 0218.500HXP F2416-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. 16 FRONT PANEL CONTROLS 1 2 3 6 5 4 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. 3. OUT CONNECTOR. This N-type connector provides the output to a 100 kΩ (or higher) load. Caution: Voltages as high as ±500V 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. 4. 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 > 1kΩ 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 17 “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. 18 REAR PANEL CONTROLS 4 5 8 GATE LAN 1 3 GRN=LNK YEL=ACT 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. 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 width tracks the pulse width on this input, or the output pulse width can be set independently. 19 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. LAN Connector and Indicator. (Optional feature. Present on -TNT units only.) The -TNT option "Internet-enables" Avtech pulse generators by adding this standard Ethernet port to the rear panel, in addition to the IEEE-488.2 GPIB and RS-232 ports normally found on "-B" units. Commands are sent using the standard Telnet protocol. The SCPI-compliant command set is the same as that used for GPIB and RS-232 control. The -TNT option uses the Dynamic Host Configuration Protocol (DHCP) to obtain its network address. A DHCP server must be present on the local network for the -TNT option to operate properly. 9. AMP Connector. This connector, if present, is not used. 20 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: SYNC OUT (generated by the internal oscillator) 100 ns, FIXED 3V, FIXED DELAY > 0 PULSE WIDTH AMPLITUDE, VARIABLE MAIN OUTPUT Figure A 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 AMPLITUDE, VARIABLE MAIN OUTPUT Figure B The next figure illustrates the relationship between the signal when an external TTLlevel trigger is used: 21 > 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, VARIABLE MAIN OUTPUT 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. 22 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. 23 OUTPUT IMPEDANCE The AVR-GHV1-B has an output impedance (i.e., an internal resistance in series with the output) of 50 Ohms, to provide transmission line back-matching and short-circuit protection. The rise and fall times are fixed at less than 40 ns. However, since the output impedance is 50Ω, the rise and fall times will degrade if cable lengths longer than 1 meter (3 feet) are used on the output, due to the cable capacitance. The maximum usable cable length is 2 meters (6 feet). LOAD IMPEDANCE The AVR-GHV1-B can drive load impedances of 100 kΩ or higher. It is NOT designed to drive 50 Ω loads or highly capacitive loads. (The AVR-GHV1-B is tested with capacitive loads of 330 pF. Load capacitance should not exceed 330 pF.) BURST GENERATION (-BR OPTION) The waveforms given above assume that a single output pulse is generated for each trigger event (regardless of the source). However, when the burst mode feature is used on units with the -BR option, the instrument can generate 1-500 pulses for each individual trigger event. The number of output pulses in each burst can be adjusted from 1 to 500 using the front-panel controls (using the “N” menu), or by a computer command. The time between pulses (i.e., from the falling edge of one pulse to the rising edge of the next pulse) can also varied from 1 ms to 1.0 seconds from the front panel (using the “BUR” menu), or by computer command. The figure below shows burst mode operation (i.e., N > 1) used with internal triggering: PERIOD = 1 / FREQUENCY SYNC OUT (generated by the internal oscillator) DELAY (VARIABLE) PULSE WIDTH (VARIABLE) BURST COUNT (N), VARIABLE FROM 1 TO 500. (N = 3, IN THIS EXAMPLE) MAIN OUTPUT BURST PULSE SEPARATION The figure below shows burst mode operation used with external triggering: 24 > 50 ns TRIG (external input) TTL LEVELS (0 and 3V-5V) PROPAGATION DELAY (FIXED) SYNC OUT DELAY (VARIABLE) PULSE WIDTH (VARIABLE) BURST COUNT (N), VARIABLE FROM 1 TO 500. (N = 3, IN THIS EXAMPLE) MAIN OUTPUT BURST PULSE SEPARATION The burst mode may also be used with the front-panel “Single Pulse” pushbutton as a trigger source. (Pressing the pushbutton will actually generate a single burst, rather than a single pulse, in this mode.) Computer commands can also trigger a burst. To control the burst count and timing from the front-panel, use the “N” and “BUR” menus. To control them using computer commands, use the SOURce:PULSe:COUNt and SOURce:PULSe:SEParation commands, as described in the programming manual. The pulse spacing is constrained by several factors: 1. The maximum PRF limitation of the instrument applies within the burst. That is, timing between two consecutive leading edges must lie between a minimum of 1/PRFMAX and a maximum of 1.0 seconds, where PRFMAX is the maximum pulse repetition frequency specification for the instrument. For this instrument, the maximum PRF for the instrument is 1 kHz, so the time between two leading edges within the burst may not be smaller than 1 millisecond. The total number of pulses per second (i.e., Trigger Frequency x Burst Count) must also be less than 1 kHz. 2. The maximum duty cycle limitation of the instrument can not be exceeded inside the burst. Within the burst, the duty cycle may be calculated using DCBURST = 100% x Pulse Width / (Pulse Width + Pulse Separation). The total average duty cycle is equal to DCAVG = 100% x Pulse Width x Burst Count x Trigger Frequency. Both DCBURST and DCAVG must be less than the rated maximum duty cycle of the instrument. For this instrument, the maximum duty cycle is 80%. 25 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 1 kHz or if the load impedance is too low (< 100 kΩ or > 330 pF). 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 PW to a minimum. • Never apply an externally generated voltage to the output port. • Reduce the amplitude below 100 Volts before changing the output polarity. Note that internal protection circuits will prevent the polarity from switching when the amplitude is set higher than ±100V, until the internal power supplies have discharged the voltage on the internal energy-storage capacitors to below ±100V. This may take several seconds. • Use the correct load impedance (> 100 kΩ and < 330 pF). • Keep output cable lengths to 2 meters (6 feet) or less. 26 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. REAL-TIME OSCILLOSCOPE AVTECH PULSER MAIN OUTPUT CONNECTOR SCOPE PROBE CHANNEL A TEST LOAD AC POWER SYNC OUTPUT 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 100 kΩ (or higher) load to the OUT connector and place the scope probe across this load. The load resistor must have a voltage rating of at least 500V. 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. If a 100 kΩ resistor is used, the worst-case power dissipation is 2.5 Watts. (Ohmite “OY” ceramic composition resistors - http://www.ohmite.com - are recommended for such applications. These resistors are readily available from http://www.digi-key.com/ and other distributors.) 2. Set the oscilloscope to trigger externally with the vertical setting at 100 Volts/div and the horizontal setting at 1 us/div. Be sure that your oscilloscope and probe setup can handle the maximum amplitude of 500V. A high-voltage attenuator might be necessary to avoid damaging the probe and oscilloscope. 27 3. Turn on the AVR-GHV1-B. The main menu will appear on the LCD. 4. To set the AVR-GHV1-B 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 1 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 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. 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. Press the CHANGE button. The output submenu will appear. 28 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 +200V (or -200V for "-N" instruments). Observe the oscilloscope. You should see 1 us wide, 200V pulses. Rotate the ADJUST knob. The amplitude as seen on the oscilloscope should vary. Reduce the amplitude to 50V (or -50V for "-N" instruments), using the adjust knob. For "-PN" units only: Change the output polarity by pressing the “+/-” button. The output amplitude should become negative, and you should see -50V pulses on the oscilloscope. (Avoid switching polarity when the amplitude is higher than 100V. Reduce the amplitude first.) 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. 29 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 1 us pulse:delay 2 us volt 200 output on (resets the instrument) (selects internal triggering) (sets the frequency to 1000 Hz) (sets the pulse width to 1 us) (sets the delay to 2 us) (sets the amplitude to 200 V) (turns on the output) For triggering a single event, this sequence would be more appropriate: *rst trigger:source hold pulse:width 1 us pulse:delay 2 us output on volt 200 trigger:source immediate trigger:source hold output off (resets the instrument) (turns off all triggering) (sets the pulse width to 1 us) (sets the delay to 2 us) (turns on the output) (sets the amplitude to 200 V) (generates a single non-repetitive trigger event) (turns off all triggering) (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 1 us pulse:delay 2 us volt 200 output on (resets the instrument) (selects internal triggering) (sets the pulse width to 1 us) (sets the delay to 2 us) (sets the amplitude to 200 V) (turns on the output) These commands will satisfy 90% of your programming needs. 30 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.

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. 33 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. WIRING DIAGRAMS WIRING OF AC POWER 3 Do not attempt any repairs on this instrument beyond the fuse replacement procedures described in the manual. Contact Avtech if the instrument requires servicing.
