When testing is finished, turn off the instrument, open the DUT door, and gently pry the
daughterboard up out of the socket.
Remove the DUT and A23-type battery, if used.
CUSTOMER-SPECIFIC -WDIP16A DAUGHTERBOARD
Units with the -WDIP16A option are provided with 16 assembled customized
daughterboards, instead of the 8 standard DIP8 daughterboards. These customer-specific
customized daughterboards provide a wide-DIP16 socket (with 0.6” row spacing),
intended to mate to a user-supplied carrier PCB for the user’s SMT device under test
(DUT). The pinout of the wide-DIP16 socket is:

Function
1-4 1 HV pulse will be applied to these pins. These pins are shorted
together on the daughterboard. The HV is accessible for monitoring on
a rear-panel BNC connector.
5-8 2 These pins are shorted together on the daughterboard, but have no
external connection or function.
9, 16 3, 10 GND2 (non-floating). These pins are shorted together on the
daughterboard.
10 4 No connection
11 5 No connection
12 6 DOUT. A probe point will be provided to access this signal. No pullup
or pulldown resistors are provided.
13 7 CLK. A probe point will be provided to access this signal. No pullup or
pulldown resistors are provided.
14 8 VCC1, +3.3V. This will be generated by a linear regulator (from VCC2)
on the daughterboard.
15 9 VCC2, +5V. This will be supplied by the instrument.
