INTRODUCTION
The AVOZ-D2-B is a high performance, GPIB and RS232-equipped pulser generator
that features five identical outputs. These outputs can either be combined to drive a
single low-impedance (10 Ohm) load, or can be used separately to drive multiple 50
Ohm loads simultaneously. This unique flexibility makes the AVOZ-D2-B ideal for
testing high-current laser diode arrays, as well as testing multiple identical lower-current
devices (for instance, production testing of attenuators).
The AVOZ-D2-B is capable of generating 0 to 700V on each of its five identical outputs,
at repetition rates up to 2.5 kHz. The pulse width is variable from 200 ns to 10 us, and
the duty cycle may be as high as 0.05%. Rise and fall times are fixed at less than 100
ns. The AVOZ-D2-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 output pulse width can be set to follow an input trigger pulse width.
The five outputs are all wired to the same point internally, and thus share common
timing and amplitude controls. If the five outputs are connected to a common 10 Ohm
load, the AVOZ-D2-B can deliver up to 70 Amps of pulsed current to the load.
An optional output module is available to simplify the connection of a single load to the
multiple outputs. Cable kits are also optionally available.
The output voltage polarity depends on the model number:
"-P" units: 0 to +700 Volts
"-N" units: 0 to -700 Volts
The AVOZ-D2-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.
The instrument is protected against overload conditions (such as short circuits) 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.
This instrument is intended for use in research, development, test and calibration
laboratories by qualified personnel.
