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.
