For positive pulse mode, the “AMP1” front-panel setting must be set to a positive value
AND
the daughterboard must be installed in the socket so that it is in the left-most
position (when viewed from the DUT area door opening), closest to the socket lever,
like this:
DAUGHTERBOARD INSTALLED FOR
POSITIVE
PULSE OPERATION
In this configuration, pins J2:1 to J2:16 on the daughterboard mate to pins 5 to 20 of the
ZIF socket, and pins J1:1 to J1:16 on the daughterboard mate to pins 36 to 21 on the
ZIF socket. The positive pulse generator (ZIF pin 20) applies a pulse to J2:16, and this
pulse is also fed to the BNC connector on the panel through a daughterboard track to
J2:12 / ZIF pin 16. VCC2 is applied to ZIF pin 36 / J1:1. Chassis ground (GND2) is
provided at ZIF pins 21-24 / J1:13-16. The ground-referenced logic output is provided
at ZIF pin 29 / J1:8.
For negative pulse mode, the “AMP1” front-panel setting must be set to a negative
value
AND
the daughterboard must be installed in the socket so that it is in the right-

Unused space
in this area
Daughterboard is
installed as far to the
left as possible, close
to the socket lever.
These silkscreened arrows must
always point in the same direction.
