INTRODUCTION
The AVR-E3A-B is a high performance, GPIB and RS232-equipped instrument capable
of generating 100V into 50Ω loads. The rise time is less than 1.2 ns. The fall time is
less than 3 ns for pulse widths less than 15 ns, and less than 2 ns for for wider pulses.
The pulse width is variable from 10 ns to 500 ns, subject to a 2% duty cycle limit. The
maximum pulse repetition frequency is 200 kHz.
Instruments with the "-P" model suffix can generate 0 to +100V, whereas instruments
with the "-N" model suffix can generate 0 to -100V. Instruments with the "-PN" suffix can
generate both polarities.
A 50 Ohm load is required for proper operation. The output stage may be damaged if
the output is not terminated into a 50Ω load.
The AVR-E3A-B is a highly flexible instrument. Aside from the internal trigger source, it
can also be triggered or gated by external TTL-level signals. A front-panel pushbutton
or a computer command can also be used to trigger the instrument.
The AVR-E3A-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.
This instrument is intended for use in research, development, test and calibration
laboratories by qualified personnel.
AVAILABLE OPTIONS
The AVR-E3A-B is available with several options, including:
-EA Option: the amplitude can be controlled by an externally generated 0 to +10V
analog control voltage.
-OS Option: an externally generated DC offset can be added to the output.
-R5 Option: 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.
-TNT Option: Adds a rear-panel Ethernet connector, providing Telnet-based remote
control from a network.

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 (info@avtechpulse.com) 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 (info@avtechpulse.com) if you require assistance.

1. POWER Switch. This is the main power switch. When turning the instrument on,
there may be a delay of several seconds before the instrument appears to respond.
2. OVERLOAD Indicator. When the instrument is powered, this indicator is normally
green, indicating normal operation. If this indicator is yellow, an internal automatic
overload protection circuit has been tripped. If the unit is overloaded (by operating
at an exceedingly high duty cycle or by operating into a very low impedance), the
protective circuit will disable the output of the instrument and turn the indicator light
yellow. The light will stay yellow (i.e. output disabled) for about 5 seconds after
which the instrument will attempt to re-enable the output (i.e. light green) for about 1
second. If the overload condition persists, the output will be disabled again (i.e. light
yellow) for another 5 seconds. If the overload condition has been removed, the
instrument will resume normal operation.
This overload indicator may flash yellow briefly at start-up. This is not a cause for
concern.
Note that the output stage will safely withstand a short-circuited load condition.
3. OUT CONNECTOR. This SMA connector provides the main output signal, into load
impedances of 50Ω .
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 > 50Ω 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
16
detail.

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.)
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.
18
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. (Optional feature. Present on "-EA" units only.) The output amplitude
can be set to track the voltage on this input. Zero Volts in corresponds to zero
amplitude output, and +10V in corresponds to maximum amplitude out. This mode is
activated by selecting "Ext Control" on the front-panel amplitude menu, or with the
"source:voltage external" command.
10. OS Connector. (Optional feature. Present on "-OS" units only.) The desired DC offset
is applied to this connector. Internally, it is connected to the output centre conductor
via a high quality RF inductor. Do not exceed ±50V, 250 mA. When not used, the OS
input should be connected to ground.

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.
•
OUT. This is the main output. The maximum output voltage is 100V.
•
SYNC. 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.
All waveforms are shown with positive amplitudes.

As before, if the delay is negative, the order of the SYNC and OUT pulses is reversed.
In general, 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.
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.)
21
WARNING: The output stage may be damaged if triggered by an external signal at a
pulse repetition frequency greater than 100 kHz (10 kHz for units with the -W option).
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
OPTIONAL FEATURES
RACK MOUNTING, -R5 OPTION
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.
DC OFFSET, -OS OPTION
A DC offset can be added to the output signal by applying a DC voltage to the rear-panel
OS connector. Internally, it is connected to the output centre conductor via a high quality
RF inductor. Do not exceed ±50V, 250 mA.
ELECTRONIC AMPLITUDE CONTROL, -EA OPTION
The output amplitude can be set to track the voltage on this input. Zero Volts in
corresponds to zero amplitude output, and +10V in corresponds to maximum amplitude
out. This mode is activated by selecting "Ext Control" on the front-panel amplitude menu,
or with the "source:voltage external" command.
23
PROTECTING YOUR INSTRUMENT
TURN OFF INSTRUMENT WHEN NOT IN USE
The lifetime of the switching elements in the pulse generator module is proportional to
the running time of the instrument. For this reason the prime power to the instrument
should be turned off when the instrument is not in use. In the case of failure, the
switching elements are easily replaced following the procedure described in a following
section.
DO NOT EXCEED 200 kHz
The output stage may be damaged if triggered by an external signal at a pulse
repetition frequency greater than 200 kHz.
USE A 50Ω LOAD
A 50 Ohm load is required for proper operation. The output stage may be damaged if
the output is not terminated into a 50Ω load.
24
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.
A 50 Ohm load is required for proper operation. The output stage may be damaged if
the output is not terminated into a 50Ω load.
The AVR-E3A-B output may be observed using either a high-speed sampling
oscilloscope, or a slower real-time oscilloscope. To accurately observe these rising
and falling edges, a sampling oscilloscope with a bandwidth of 2 GHz is required.
However, if the rising and falling edges do not need to be accurately observed, it may
be more convenient to use a real-time oscilloscope. The two basic test arrangements
are outlined in the figures below:

BASIC TEST ARRANGEMENT, WITH A REAL-TIME OSCILLOSCOPE
1. Connect the pulse generator to an oscilloscope using one of the two methods
shown above. Note that:
a) If using a sampling oscilloscope, the use of 50 dB attenuator at the sampling
scope vertical input channel will ensure a peak input signal to the sampling
scope of less than 1 Volt.
b) If using a realtime oscilloscope, a 50 Ohm load must be used to terminate the
output.
c) The SYNC output channel provides TTL level signals (approximately 0 and
+3V). To avoid overdriving the TRIG input channel of some sampling
oscilloscopes, a 20 dB attenuator should be placed at the input to the scope
trigger channel.
d) The bandwidth capability of components and instruments used to display the
pulse generator output signal (attenuators, cables, connectors, etc.) should
exceed 2 GHz.
e) Set the oscilloscope to trigger externally with the vertical setting at 500 mV/div
for sampling oscilloscopes, or 50 V/div for real-time scopes, and the horizontal
setting at 20 ns/div.
2. Turn on the AVR-E3A-B. The main menu will appear on the LCD.
3. To set the AVR-E3A-B to trigger from the internal clock at a PRF of 10 kHz:
a) The arrow pointer should be pointing at the frequency menu item. If it is not,
press the MOVE button until it is.
26
b) Press the CHANGE button. The frequency submenu will appear. Rotate the
ADJUST knob until the frequency is set at 10 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.
4. 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) 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.
5. To set the pulse width to 100 ns:
a) Press the MOVE button until the arrow pointer is pointing at the pulse width
menu item.
b) Press the CHANGE button. The pulse width submenu will appear. Rotate the
ADJUST knob until the pulse width is set at 100 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.
6. At this point, nothing should appear on the oscilloscope.
7. 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.
27
8. 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 (or -100V for "-N" models).
c) Observe the oscilloscope. You should see 100 ns wide, 100V pulses. If you do
not, you may need to adjust the delay setting to a value more compatible with
your sampling oscilloscope. Repeat step 4 if required. You may also need to
adjust the sampling scope controls.
d) Rotate the ADJUST knob. The amplitude as seen on the oscilloscope should
vary. Return it to 100V.
e) ("-PN" units only) Press the +/- button on the front panel. The amplitude as
seen on the oscilloscope should flip polarity, to -100V.
f)
Press CHANGE to return to the main menu.
9. Try varying the pulse width, by repeating step (5). As you rotate the ADJUST knob,
the pulse width on the oscilloscope will change. It should agree with the displayed
value.
This completes the operational check.

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 50 ns
pulse:delay 20 ns
volt:ampl 100
output on
(resets the instrument)
(selects internal triggering)
(sets the frequency to 1000 Hz)
(sets the pulse width to 50 ns)
(sets the delay to 20 ns)
(sets the amplitude to +100 V)
("-N" units should use "volt:ampl -100)
(turns on the output)
For triggering a single event, this sequence would be more appropriate:
*rst
trigger:source hold
pulse:width 50 ns
output on
volt:ampl 100
(resets the instrument)
(turns off all triggering)
(sets the pulse width to 50 ns)
(turns on the output)
(sets the amplitude to +100 V)
("-N" units should use "volt:ampl -100)
trigger:source immediate (generates a single non-repetitive trigger event)
trigger:source hold
(turns off all triggering)
output off
(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 50 ns
pulse:delay 1 us
volt:ampl 100
output on
(resets the instrument)
(selects internal triggering)
(sets the pulse width to 50 ns)
(sets the delay to 1 us)
(sets the amplitude to +100 V)
("-N" units should use "volt:ampl -100)
(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 (info@avtechpulse.com) 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.
