INTRODUCTION
The Avtech AV-1030-B is a versatile, general-purpose, low-cost, GPIB and RS232-
equipped 10 MHz laboratory pulse generator, useful everywhere from undergraduate
university classrooms to the most advanced research and development laboratories.
This pulse generator features variable pulse repetition frequency (PRF), delay, pulse
width, and amplitude. It also features an exceptionally fast 300 ps rise and 350 ps fall
times.
The AV-1030-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. In the external
trigger mode, the output pulse width can be set by the pulse generator, or it can be set
to follow the input trigger’s pulse width.
The main output has all of its characteristics variable, and is designed to drive 50Ω
loads. (A 50Ω load is required for proper operation.) The main output is AC-coupled.
Two logic outputs (TTL and ECL) have approximately the same timing characteristics
as the main output, but have their amplitudes fixed at standard logic levels.
A synchronizing trigger output is also supplied, for triggering oscilloscopes and other
test equipment (50 ns wide, +3V into 50Ω).
Several points should be noted when operating this instrument:
This unit requires a 50 ohm load.
The maximum main output duty cycle is 10%.
The main output is AC-coupled.
The AV-1030-B features front panel keyboard and adjust knob control of the output
pulse parameters along with a four line by 40 character back-lit LCD display of the
output amplitude, polarity, pulse width, pulse repetition frequency, source resistance
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 and development laboratories.

REGULATORY NOTES
FCC PART 1
This device complies with part 1 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.

INSTALLATION
VISUAL CHECK
After unpacking the instrument, examine to ensure that it has not been damaged in
shipment. Visually inspect all connectors, knobs, liquid crystal displays (LCDs), and the
handles. Confirm that a power cord, a GPIB cable, and two instrumentation manuals
(this manual and the “Programming Manual for -B Instruments”) are with the instrument.
If the instrument has been damaged, file a claim immediately with the company that
transported the instrument.
POWER RATINGS
This instrument is intended to operate from 100 - 240 V, 50 - 60 Hz.
The maximum power consumption is 57 Watts. Please see the “FUSES” section for
information about the appropriate AC and DC fuses.
This instrument is an “Installation Category II” instrument, intended for operation from a
normal single-phase supply.
CONNECTION TO THE POWER SUPPLY
An IEC-320 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. The other end of the detachable
power cord plugs into the local mains supply. Use only the cable supplied with the
instrument. The mains supply must be earthed, and the cord used to connect the
instrument to the mains supply must provide an earth connection. (The supplied cord
does this.)
Warning: Failure to use a grounded outlet may result in injury or death due to
electric shock. This product uses a power cord with a ground connection. It must be
connected to a properly grounded outlet. The instrument chassis is connected to the
ground wire in the power cord.
The table below describes the power cord that is normally supplied with this instrument,
depending on the destination region:
