Avtech AVR-E1-B, Instructions Manual

Page: 5 / 46

INTRODUCTION
The AVR-E1-B is a high performance, GPIB and RS232-equipped instrument capable
of generating up to 20V into 50Ω loads. The rise time (20%-80%) is less than 300 ps,
and the fall time (80%-20%) is less than 600 ps.
On standard models, the output pulse width is variable from 10 ns to 200 ns, at
repetition rates up to 200 kHz.
Models with the -W1 option have an output pulse width variable from 1 ns to 200 ns, at
repetition rates up to 200 kHz.
Models with the -W2 option have an output pulse width variable from 50 ns to 5 us, at
repetition rates up to 20 kHz.
Models with the -W3 option have an output pulse width variable from 1 ns to 5 us, at
repetition rates up to 20 kHz.
Instruments with the "-P" model suffix can generate up to +20V, whereas instruments
with the "-N" model suffix can generate up to -20V. 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-E1-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-E1-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.
