Avtech AVR-E3A-B, Instructions Manual

Page: 5 / 40

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, and the fall time is
less than 2.5 ns. 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 up to +100V, whereas instruments
with the -N model suffix can generate up 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.
