BASIC TEST ARRANGEMENTS
The figure below shows the basic test arrangement for the AVRQ-5-B, with one
possible DUT daughterboard configuration, with the daughterboard installed for positive
pulse operation and a high-current input bias on the LED:
In the above drawing, an HCPL-2601 current-drive opto-coupler is installed on the
daughterboard, and the daughterboard is configured to drive the opto-coupler input with
~ 16 mA of current (using VCC1 and a 220 Ohm resistance). The daughterboard is
positioned as close as possible to the socket lever in order to connect the
daughterboard to the positive pulse circuitry.
