INTRODUCTION

The AVO-6C-B is a high performance, GPIB and RS232-equipped instrument capable
of generating up to 5 A at repetition rates up to 10 kHz. The pulse width is variable from
50 ns to 5 us, and the duty cycle may be as high as 1%. Rise and fall times are fixed at
less than 12 ns. The AVO-6C-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 Model AVO-6C1-B variant has an extended pulse width range (50 us maximum,
compared to 5 us for the standard AVO-6C-B). The AVO-6C1-B is not available with the

-OS option. In all other respects, they are identical.

The AVO-6C-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.

5

The instrument is protected against overload conditions 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.

The AVO-6C-B consists of two parts, the mainframe and the output module. The
mainframe is a voltage pulser, which generates up to 250V (V

). The output module

OUT

contains a 50Ω series resistance. The diode load is connected in series with this
resistance, so that the current through the diode is normally given by:

I

where V

= (V

DIODE

is the voltage drop across the diode. An additional resistance (R

DIODE

OUT

– V

DIODE

) / 50Ω

SENSE

) can
be placed in series with the load, for current monitoring purposes. In this case, the
diode current is given by:

I

DIODE

= (V

OUT

– V

) / (50Ω + R

DIODE

SENSE

)

Alternatively, a fast current probe may be used to monitor the current waveform.
Factory testing is conducted using a Tektronix CT2 or Pearson 2878 current
transformer. (This technique tends to introduce less waveform distortion than the
sensing resistor method.)

The output voltage polarity depends on the model number:

"-P" units: up to +250 Volts

"-N" units: up to -250 Volts

"-PN" units: up to ±250 Volts

This instrument is intended for use in research, development, test and calibration
laboratories by qualified personnel.

6

AVAILABLE OPTIONS

The AVO-6C-B is available with several options:

-M Option: a monitor output is provided.

-OS Option: an externally generated DC offset can be added to the output. (Not
available for the AVO-6C1-B.)

-R5 Option: This is the optional rack-mounting kit. The R5 rack-mount kit may also be
ordered separately.

-S Option: Diode socket mounting option. Customer must supply socket specifications.

-VXI Option: Adds a rear-panel Ethernet connector, allowing the instrument to be
remotely controlled using the VXI-11.3, ssh (secure shell), telnet, and http (web)
protocols. In particular, the VXI-11.3 features allows software like LabView to control an
instrument using standard VISA communications drivers and network cabling, instead of
using old-style GPIB cabling. (This eliminates the need for a GPIB controller card and
its proprietary drivers.)

7

HIGH-VOLTAGE PRECAUTIONS

CAUTION: This instrument provides output voltages as high as 250 Volts under

normal operating conditions, and generates > 250V 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.

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 ([e-mail]) 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 ([e-mail]) if you require assistance.

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.

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 > 1kΩ 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
detail.

5. KEYPAD.

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.

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. 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.

21

9. OUT CONNECTOR. This SMA connector is connected to the output module, when the

output module is used to drive a diode load. If the output module is not used, this
output will generate up to 250V into a load impedance of 50Ω.

Caution: Voltages as high as ±250V 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.

GENERAL INFORMATION

AMPLITUDE CONTROL

The AVO-6C-B consists of two parts, the mainframe and the output module. The
mainframe is a voltage pulser, which generates up to +250V (assuming that the model
is a “-P” positive unit, or a dual-polarity model operating in the positive mode). The
output module contains a 50Ω series resistance. The diode load is connected in series
with this resistance, so that the current through the diode is normally given by:

I

DIODE

= (V

OUT

– V

DIODE

) / 50Ω

22

where V

is the voltage drop across the diode.

Output Module Functional Equivalent Circuit

(The equivalent circuit is shown for positive outputs. For “-N” instruments, and the
negative output circuit of the dual-polarity “-PN” instruments, the polarities are negative
and diodes are reversed in direction.)

On units with the -M option, a monitor output is provided, as shown above. When the
monitor output is terminated with a 50 Ohm resistance, the monitor output provides an
attenuated (approximately 20 dB) replica of the input signal to the output module.

An additional resistance (R

) can be placed in series with the diode load, for current

monitoring purposes. In this case, the diode current is given by:

23

I

DIODE

= (V

OUT

– V

) / (50Ω + R

)

Alternatively, a fast current probe may be used to monitor the current waveform.
Factory testing is conducted using a Tektronix CT2 or Pearson 2878 current
transformer. (This technique tends to introduce less waveform distortion than the
sensing resistor method.)

Models with the -OS option have a bias-tee circuit built into the output module, to allow
an externally-generated offset to be added to the output.

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).

The voltage developed across an inductance L (in Henries), when the current is
changing at a rate given by dI

/ dt (in Amps/sec), is: V

BASIC TEST ARRANGEMENT - WITHOUT OUTPUT MODULE

The AVO-6C-B can be tested initially without the supplied output module. If the output
module is not used, the mainframe output generates up to +250 Volts (for -P units), or
up to -250V (for -N units), into a 50 Ohm load, as illustrated below:

If the AVO-6C-B is operated at its maximum duty cycle, the worst-case power
dissipation in the output module is (250V × 5A × 1%) = 12.5 Watts. When operating
near 1% duty cycle, the output module should be bolted to a heatsink, using the tapped
screw holes on the bottom of the module.

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:

internal oscillator)

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.)

27

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.

28

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.

For the first test, the output module is not used.

1.Connect a cable from the SYNC OUT connector to the TRIG input of an oscilloscope.
Connect a 5W (or higher) 50Ω load to the OUT connector on the rear panel of the
mainframe and place the scope probe across this load. Set the oscilloscope to
trigger externally.

the current probe (Tektronix CT2 or Pearson 2878) should correspond to a
measurement of 5 A of current. (A series-connected current-sensing resistor may
also be used to measure the current, but this method often produces pronounced
overshoot on the rising and falling edges. This is a measurement artefact, and is
not present on the actual current waveform. This may be confirmed by using a
current probe.)

d)Press CHANGE to return to the main menu.

9.Repeat the last step, but set the amplitude to zero.

10.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 (resets the instrument)
trigger:source internal (selects internal triggering)
frequency 1000 Hz (sets the frequency to 1000 Hz)
pulse:width 1 us (sets the pulse width to 1 us)
pulse:delay 2 us (sets the delay to 2 us)
volt 200 (sets the amplitude to 200 V)
output on (turns on the output)

For triggering a single event, this sequence would be more appropriate:

*rst (resets the instrument)
trigger:source hold (turns off all triggering)
pulse:width 1 us (sets the pulse width to 1 us)
output on (turns on the output)
volt 200 (sets the amplitude to 200 V)
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 input:

*rst (resets the instrument)
trigger:source external (selects external triggering)
pulse:width 1 us (sets the pulse width to 1 us)
pulse:delay 2 us (sets the delay to 2 us)
volt 200 (sets the amplitude to 200 V)
output on (turns on the output)

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.)

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 before opening the instrument.

There are no user-adjustable internal circuits. For repairs other than fuse replacement,
please contact Avtech ([e-mail]) to arrange for the instrument to be
returned to the factory for repair.

Caution: High voltages are present inside the instrument during normal operation.

Do not operate the instrument with the cover removed.

35

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 50Ω loads using shielded 50Ω coaxial cables. Unused
outputs should be terminated with shielded 50Ω coaxial terminators or with shielded
coaxial dust caps, to prevent unintentional electromagnetic radiation. All cords and
cables should be less than 3m in length.

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.

"UV- ON" IS HIGH IF:

1) "UV+ HIGH" IS LOW, AND

2) "POL" IS LOW.

"UV+ ON" IS HIGH IF:

1) "UV- HIGH" IS LOW, AND

2) "POL" IS HIGH.

IF THE POLAR ITY IS SWITCHED, AND THE OPPOSITE ULTRAVOLT IS TOO HIGH, NO TRIGGERS OCCUR UNTIL THE VOLTAGE FALLS.

THIS DRIVES THE OUTPUT POLARITY RELAY.
