Standard AVR-EB2A-B models include one AVX-CA-AXPOST diode test jig. The
instrument mainframe is connected to the test jig using one coaxial cable and one DB-9
control cable. The test jig has a hinged lid, which must be fully closed to protect the
user from high voltages. The output will be automatically disabled if the lid is left open.
The AVX-CA-AXPOST has easy-to-use spring-loaded push-posts for axial packages
with body length of up to 0.25” (and diameters up to 0.5”), including DO-35, DO-41 and
Microsemi Axial Type E packages (0.185" x 0.135" body, max). Lead bending is not
required to insert these packages.
The AVR-EB2A-B may also be provided with different or additional a customized test
jigs, to meet particular customer package requirements.
The output from the test jig must be connected (using the supplied cable and 20 dB
attenuator) to the 50 Ohm input of a high-bandwidth (> 1 GHz) user-supplied
oscilloscope. The voltage on the output is proportional to the current through the DUT.
By observing the current waveform through the DUT, the reverse recovery time may be
determined.
The AVR-EB2A-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 AVR-EB2A-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 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.
