INTRODUCTION
The Model AVOZ-A3-B pulse generator is designed for pulsing laser diode and other
low impedance loads with rectangular pulses as high as 100V into 1Ω (i.e. 100 Amps)
with < 30 ns rise times (< 35 ns for units with the -OS option). The current and voltage
polarities depend on the model number:
-P units: up to +100 V amplitude (0 to +100 Amps)
-N units: up to -100 V amplitude (0 to -100 Amps)
-PN units: up to ±100 V amplitude (0 to ±100 Amps)
The pulse repetition frequency can vary from 1 Hz to 20 kHz, and pulse widths can vary
from 50 ns to 2 us. The maximum duty cycle is 0.1%, and the maximum average output
power is 10 Watts.
The Model AVOZ-A3-B pulse generator is a voltage pulser. The current amplitude is
determined by Ohm’s Law. That is, the current is the output voltage divided by the load
resistance. The load resistance should be approximately 1Ω to attain a peak current of
100 A.
The loads can be connected to the pulse generator using the convenient AV-CLZ1-60
transmission line cable assembly, which has a 1Ω characteristic impedance (Z0), and is
terminated with a DB-37 male connector. A sample connectorized test load is provided.
The AVOZ-A3-B can be controlled from the front panel, or via a computer connected to
the IEEE 488.2-compliant GPIB port, or the RS-232 serial port.
This instrument is intended for use in research, development, test and calibration
laboratories by qualified personnel.

The resolution of the timing parameters (pulse width, delay, period) varies,
but is always better than 0.15% of (|set value| + 20 ns).
The amplitude resolution is < 0.1% of the maximum amplitude (excluding the AVOZ-B4-B).
Settings accuracy:
Typically ± 3% (plus ±1V or ± 2 ns) after 10 minute warmup, at low duty cycles13. For high-accuracy applications
requiring traceable calibration, verify the output parameters with a calibrated oscilloscope.

Chassis material:
Anodized aluminum, with blue plastic trim
Optional rack-mount kit:
Add -R5 suffix.
Temperature range:
+5°C to +40°C
1) -B suffix indicates IEEE-488.2 GPIB and RS-232 control of pulse amplitude, pulse width, delay and PRF. (See http://www.avtechpulse.com/gpib).
2) For remote analog electronic control (0 to + 10V) of the amplitude, suffix model number with -EA. Electronic control units also include standard front-panel controls. Not
available for the AVOZ-B4-B.
3) For operation at voltage amplitudes of less than 10% of the full-scale voltage, better results may be obtained by setting the amplitude near full-scale and increasing the
load impedance accordingly.
4) Required to limit output current. For applications where additional resistance must be added in series with the device under test, Avtech recommends connecting multiple
Ohmite OY-series (http://www.ohmite.com) ceramic composition resistors in parallel to create a high-power, low-inductance effective resistance.
5) Indicate desired polarity by suffixing model number with -P or -N (i.e. positive or negative) or -PN for dual polarity option.
6) The supplied test load is for low-duty-cycle basic operational tests only. The power rating of the load is 5 Watts. it is not capable of supporting the instrument's full
maximum average output power. See http://www.avtechpulse.com/accessories/ for details about the AV-CTL series of test loads.
8
7) The AVOZ-B4-B requires a user-supplied 0 to 110V DC power supply that is capable of supplying the maximum average power output of the instrument (i.e., 400 Watts
worst-case). The polarity of the power supply must be the same as that of the AVOZ-B4-B. The Xantrex ( http://www.xantrex.com/) XHR 150-7 is one example of a suitable
power supply.
8) Add the suffix -VXI to the model number to specify the Ethernet port.
9) Multi-Contact (http://www.multi-contact.com or http://www.multi-contact-usa.com) ID/S6AR-N-B4S series, or similar. For mating cables, specify the -AK3 option, which
includes two 1m cables (1 red, 1 black) with 6mm safety sockets, and two 6mm safety plug to M6 stud adapters (1 red, 1 black).
10) Measured when the load resistance is equal to the minimum rated load impedance.
11) Typically < 10 ns measured at rear-panel output connector. The supplied AV-CLZ11-60 cable, if used, will degrade the rise and fall times to < 15 ns, approximately.
12) The maximum and actual amplitudes will fall by up to 25% for pulse widths less than 3 times the specified rise/fall time, due to the “rounding” of the pulse.
13) The amplitude may decrease ~10% relative to the programmed setting if the instrument is operating at or near the maximum specified duty cycle.
14) For DC offset option, suffix model number with -OS. The DC offset must be generated by a user-supplied power supply. The offset is combined with the pulse output
using a diode-OR gate, which permits the larger of the two signals (pulse versus offset) to flow to the main output. Contact Avtech ( [email protected]) if you require
higher DC current ratings or other offset configurations.

1. POWER Switch. This is the main power switch. When turning the instrument on,
there is normally a delay of 10 seconds before anything is shown on the main
display, as the internal operating system boots up.
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.
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
18
detail.

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.)
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
20
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. 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. OS Connector. (Active on units with the -OS option only.) A DC bias voltage may be
applied to this input. It will be applied to the internal “diode-OR” gate, described
elsewhere in this manual. The maximum permitted DC current is 5A.
10. OUT P. This is the main positive output, present on “-P” and “-PN” units. It is only
active when the amplitude is set to a positive value. The AV-CLZ1-60 transmission
line plugs into this DB-37 female connector. Pins 1-19 (the upper row) are
connected to the signal out, and pins 20-37 (the lower row) are connected to
ground.
Caution: Voltages as high as 100V may be present on the pins 1-19 of this
output connector. Avoid touching these conductors. Ensure that any cable, load, or
system connecting to this connector shields the high-voltage areas from the user.
11. OUT N. This is the main negative output, present on “-N” and “-PN” units. It is only
active when the amplitude is set to a negative value. The AV-CLZ1-60 transmission
line plugs into this DB-37 female connector. Pins 1-19 (the upper row) are
connected to the signal out, and pins 20-37 (the lower row) are connected to
ground.
Caution: Voltages as high as 100V may be present on the pins 1-19 of this
output connector. Avoid touching these conductors. Ensure that any cable, load, or
system connecting to this connector shields the high-voltage areas from the user.

GENERAL INFORMATION - 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 device under test. 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.
In the diagrams below, positive amplitude is assumed. (For “-N” units, the output
waveforms are inverted in polarity.)
These pulses are illustrated below for a positive delay, and internal triggering:

internal oscillator)

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.)
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
23
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.
24
GENERAL INFORMATION - OPERATING INTO A LOAD
AMPLITUDE CONTROL
The Model AVOZ-A3-B pulse generator is a voltage pulser. The current amplitude is
determined by Ohm’s Law. That is, the current is the output voltage divided by the load
resistance. More specifically:
IOUT = (VSETTING – VDIODE) / R,
where VSETTING is the set amplitude, VDIODE is the diode voltage, and R is the series
resistance (including any series resistance in the diode itself). R is normally 1Ω; it
should not be smaller than this. Avtech recommends connecting multiple Ohmite OX or
OY-series or RCD RSF2B resistors in parallel to create a high-power, low-inductance
effective resistance.
SELECTING THE SERIES RESISTANCE
The best waveforms will be obtained if the amplitude is set between 20% and 100% of
the maximum rating (i.e., 20V to 100V), and if the load resistance R is chosen to be
between 1.0 and 1.6 Ohms.
It should never be less than 1.0 Ω, or the instrument may be damaged.
For applications requiring less than the maximum possible current, best results may be
obtained if R is approximately 1.6 Ω, because this slight increase in the load resistance
will result in a faster transition times. However, the load resistance should not be
increased beyond 1.6 Ω, or the transmission line mismatch between the output
transmission line (which has a characteristic impedance of Z 0 = 1 Ω) and the load may
introduce significant ringing.
If the resistance of the device under test (DUT) is significantly higher than 1.6 Ω,
resistance should be added in parallel with the DUT so that the total equivalent
resistance is 1.6 Ω.
OUTPUT CONNECTIONS
The main output is provided on a rear-panel DB-37 female connector. Pins 1-19 of this
connector (the upper row) are connected to the signal out, and pins 20-37 (the lower
row) are connected to ground.
An AV-CLZ1-60 transmission line is supplied with the instrument. One end plugs into
the rear-panel connector. The other end is terminated with a DB-37 male connector.
Pins 1-19 of this connector (the upper row) are connected to the signal out, and pins
20-37 (the lower row) are connected to ground. The cable is reversible - either end can
be plugged into the rear panel. This cable can be ordered separately, as model AV-
25
CLZ1-60. (Lengths longer than 60 cm are also available - see
http://www.avtechpulse.com/transmission/av-clz1 for details.)
The user may connect a load to the end of the AV-CLZ1-60 transmission line using a
load that has a DB-37 female connector. To construct your own connectorized load,
consider using a Norcomp 172-037-201-001 DB-37 female connector with solder cup
pins. This is readily available from Digi-Key (http://www.digikey.com, stock number
137F-ND). Care must be taken to construct the connectorized test load to conform to
local safety standards. High voltages (up to 100V, approximately) will be present on the
load during normal operation. Pins 1-19 short be connected together to provide the
signal output, and pins 20-37 should be connected together to provide the ground.
It may be simpler to modify the supplied test load. The supplied test load has this
connector pre-installed, and a safety enclosure is provided. This test load is described
in the next section.
Caution: Voltages as high as 100V may be present on the pins 1-19 of the output
connector. Avoid touching these conductors. Ensure that any cable, load, or system
connecting to this connector shields the high-voltage areas from the user.
USING THE SUPPLIED TEST LOAD (AV-CTL1-ENC)
The supplied test load consists of a DB-37 female connector mounted on the lid of a
small aluminum box chassis. Inside the chassis, an 8 mm by 50 mm circuit board is
sandwiched between the two rows of solder cups on the rear of the connector. Four
Ohmite OY-series 3.9 Ohm resistors are connected in parallel between the two rows of
solder cups. This provides a total resistance of 3.9 Ω / 4 ≈ 1.0 Ω.
Two unused SMA connectors are provided for making connections through the chassis
wall, if desired. A 5/16" hole, plugged with a screw is also provided. The screw may be
removed to provide an access hole to the interior of the chassis.
Due to the presence of high voltages on the output (up to 100V, approximately), the lid
should be installed on the aluminum chassis so that users can not physically touch the
load.
The test load has a maximum power dissipation rating of 5 Watts. Take care not exceed
this!
This test load can be ordered separately, as model AV-CTL1-ENC. It can also be
ordered with no resistors installed, as model AV-CTLX-ENC.
The basic mechanical connection scheme for the AV-CTL1-ENC is shown below:

The diagram above shows how high-impedance oscilloscope probe can be used to
observe the waveform. However, since the load impedance is so low (1 Ohm), a 50
Ohm measurement system like that shown in the diagram below can also be used to
observe the load waveform. An attenuator should be used to avoid damaging the
oscilloscope input, since the load voltage can be as high as 100V. (Two SMA
connectors are present in the AV-CTL1-ENC test load, and either can be used to
connect the 50 Ohm coaxial cables through the chassis wall.)

The diodes are shown oriented for positive polarity. Reverse them for negative polarity
models.
There are several key points to note. As explained above, a resistance should be
added in series with the diode load, to limit the maximum current. This resistance may
also be used to monitor the current through the diode current. If connected as shown
above, the resistor voltage displayed on the oscilloscope is directly proportional to the
diode current. It is essential the low-inductance resistors be used. Several noninductive, medium power resistors should be used in parallel (for instance, four 3.9
Ohm 2W resistors). The Ohmite OY series (www.ohmite.com) or the RCD RSF2B
series (www.rcd-comp.com) are appropriate.
It is also recommended that a low-capacitance, high-voltage, ultra-fast Schottky rectifier
diode be connected for reverse-bias protection, especially for sensitive or costly
devices under test. The STMicroelectronics (www.st.com) STPS3150 is an example of
a suitable diode. Note, however, that the capacitance added by the protection diode
may degrade the output rise time slightly.
LENZ’S LAW AND INDUCTIVE VOLTAGE SPIKES
This instrument is designed to pulse resistive and diode loads and will exhibit a large
output spike when used to drive a load with significant inductance (as predicted by
LENZ'S LAW). For this reason the load should be connected to the output using low
inductance leads (as short as possible and as heavy a gauge as possible).
The voltage developed across an inductance L (in Henries), when the current is
changing at a rate given by dILOAD/dt (in Amps/sec), is: VSPIKE = L × dILOAD/dt.
For this reason, the length of leads used to connect the load to the circuit board should
be kept extremely short ( < 0.5 cm).
ATTACHING AND DETACHING LOADS
To avoid damaging the loads connected to main outputs, the loads should only be
connected to or removed from the instrument when the instrument is off. Do not connect
loads when the instrument is on and the output amplitude is not zero. This can cause
sparking.
MEASURING OUTPUT CURRENT
Two basic methods can be used to observe the current waveform through the load. The
first is to observe the voltage waveform across the resistance present in the load. If the
resistance is non-inductive, the voltage waveform will be directly proportional to the
current waveform (Ohm's Law). Keeping the parasitic inductance low is critical for
reliable measurements. If a diode is connected in series with the resistance, it may be
29
advantageous to ensure the diode is placed before the resistance, so that one end of
the resistance is grounded. This will eliminate the need for differential voltage
measurements. This method is shown in the "TEST ARRANGEMENT" section above.
Alternatively, a high-speed current probe or current transformer can be used to observe
the current waveform. One possible model is the Pearson 2878 current transformer
(http://www.pearsonelectronics.com). However, this model will not operate at the upper
end of the AVOZ-A3-B pulse width range (2 us). It may be necessary to introduce a
significant lead length (i.e., inductance) to pass the conductor through the transformer.
ADDING A DC OFFSET (-OS OPTION)
Units with the -OS option include a “diode-OR gate” for adding an externally generated
DC offset. The equivalent circuit is shown below for positive outputs:
Diode-OR

OS Connector
Output

Pulse
Generator
The diodes are reversed for negative outputs:

Generator
The diode gate “combines” the pulse signal and the DC offset. The large of the two
signals is provided to the output connector. If the pulse amplitude is lower than the DC
offset, no pulse will be seen – just the DC offset. If the pulse amplitude is higher, the
user will observe a quiescent DC offset, with a pulse superimposed on it.
The additional inductance of the Diode-OR gate degrades the switching times slightly.
The maximum permitted DC current is 5A.
31
START-UP CHECK-LIST FOR LOCAL CONTROL
1. Connect the supplied test load (AV-CTL1-ENC) to the rear-panel of the
mainframe, using the AV-CLZ1-60 cable.
2. Connect a cable from the SYNC OUT connector to the TRIG input of an
oscilloscope. Set the oscilloscope to trigger externally.
3. Connect an oscilloscope probe to the signal side of the resistors in the test load.
It may be necessary to connect the probe using the SMA feed-throughs on the
test load enclosure. On the oscilloscope, set the channel A vertical scale to 20
V/div, and the horizontal scale to 100 ns/div. (A 50 Ohm measurement system,
without a high impedance probe, can also be used if desired. This may be more
mechanically convenient. See the "TEST ARRANGEMENT" section for details.)
4. Turn on the instrument. The main menu will appear on the LCD.
5. To set the instrument to trigger from the internal clock at a PRF of 1 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 1 kHz.
c) The arrow pointer should be pointing at the “Internal” choice. If it is not, press
MOVE until it is.
d) Press CHANGE to return to the main menu.
6. To set the delay to 100 ns:
a) Press the MOVE button until the arrow pointer is pointing at the delay menu
item.
b) Press the CHANGE button. The delay submenu will appear. Rotate the
ADJUST knob until the delay is set at 100 ns.
c) Press CHANGE to return to the main menu.
7. To set the OUT pulse width to 500 ns:
a) Press the MOVE button until the arrow pointer is pointing at the “PW” menu
item.
32
b) Press the CHANGE button. The pulse width submenu will appear. Rotate the
ADJUST knob until the pulse width is set at 500 ns.
c) The arrow pointer should be pointing at the “Normal” choice. If it is not, press
MOVE until it is.
d) Press CHANGE to return to the main menu.
8. At this point, nothing should appear on the oscilloscope.
9. 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.
10.To change the OUT output amplitude:
a) Press the MOVE button until the arrow pointer is pointing at the AMP menu
item.
b) Press the CHANGE button. The amplitude submenu will appear. Rotate the
ADJUST knob until the amplitude is set at 100 V (or -100V for “-N” units).
c) Observe the oscilloscope. You should see 500 ns wide, 100V pulses on the
probe connected to the main output.
d) Press CHANGE to return to the main menu.
11.Try varying the pulse width, by repeating step (7). As you rotate the ADJUST
knob, the pulse width on the oscilloscope will change. It should agree with the
displayed value.
12.This completes the operational check.
33
CALIBRATION ADJUSTMENTS - SOFTWARE PROCEDURES
ADJUSTING AMPLITUDE ACCURACY
If it is found that the output amplitude settings (as set by the front-panel controls or
programming commands) do not agree exactly with measured values of amplitude (i.e.,
by examining the output on an oscilloscope), the amplitude calibration can be updated
using software commands.
The following procedure is suggested:
1) Connect a 1Ω high-power resistive load to the output.
2) Connect the pulse generator to a computer using the GPIB or RS232 ports.
3) Turn on the pulse generator, and set the time controls (frequency, delay, pulse
width) to typical values.
4) Turn on the outputs.
5) Set the output amplitude to 100V.
6) Observe the voltage across the load. (For example, suppose it is 104V).
7) Send the measured value to the instrument using the following command:
diag:ampl:cal 104
The internal software compares the supplied measured value to the programmed
value, and adjusts the internal calibration data to null out any differences.
8) Observe the voltage across the load again. The amplitude setting should now
agree with the measured value.
Information on more extensive timing and amplitude calibration procedures is available
at http://www.avtechpulse.com/appnote/.

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 10 Hz
pulse:width 100 ns
pulse:delay 1 us
output on
source:volt 50V
(resets the instrument)
(selects internal triggering)
(sets the frequency to 10 Hz)
(sets the pulse width to 100 ns)
(sets the delay to 1 us)
(turns on the output)
(sets the voltage amplitude to 50 Volts)
For triggering a single event, this sequence would be more appropriate:
*rst
trigger:source hold
pulse:width 100 ns
output on
source:volt 50V
trigger:source immediate
trigger:source hold
output off
(resets the instrument)
(turns off all triggering)
(sets the pulse width to 100 ns)
(turns on the output)
(sets the voltage amplitude to 50 Volts)
(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 100 ns
pulse:delay 1 us
source:volt 50V
output on
(resets the instrument)
(selects internal triggering)
(sets the pulse width to 100 ns)
(sets the delay to 1 us)
(sets the voltage amplitude to 50 Volts)
(turns on the output)
These commands will satisfy 90% of your programming needs.

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.
38
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.
TRIGGER DAMAGE
The rear-panel TRIG input, used in the external trigger mode, is protected by a diode
clamping circuit. However, the protection circuit is not foolproof, and it is possible for a
grossly excessive signal to damage the trigger circuitry on the main timing control
board (the 4×10 inch board on the right side of the instrument).
The IC that is most likely to fail under these conditions is installed in a socket. It is a
standard TTL IC in a 16-pin plastic DIP package, model 74F151 or equivalent.
If you suspect that this IC has been damaged, turn off the power and replace this IC. It
may be replaced by a 74F151, 74LS151, 74ALS151, or 74HCT151.
