7-2 E6198B Switch/Load Unit User Manual
7 Using the Custom Card
General-Purpose Breadboard
The custom card contains a breadboard area of through-holes
on 0.1" centers for soldering custom circuitry (see Figure 7-1).
TS-5430 Series I Emulation
The E8794A may be used to provide routing and breadboard
support similar to that found on the Agilent TS-5430
“Personality Board”. Digital I/O, matrix, Aux channels, routing
area and ICA interface connections that were found on the
TS-5430 “Personality Board” are also found on the E8794A.
• 64 Aux Channels (from up to two 32-Pin Matrix Cards),
• 8 system DAC channels,
• 32 event detector channels.
In addition, 32 configuration lines are brought from the custom
card to the TC connectors on the Test System Interface.
Figure 7-1 shows the J2 - J6 connectors used to route channels
and signals to/from the custom card. Each of these connectors
is routed to a breakout area on the custom card. You can make
connections from these breakout areas to your custom circuitry.
Digital I/O
A full 16 bits of digital I/O is required to emulate the TS-5430
Series I. The Switch/Load Unit provides 8 channels of digital I/O
and the custom card provides 8 channels of digital I/O. The
custom card digital I/O is the same type of 8-bit digital input
and 8-bit digital output (Open Drain) provided by the
Switch/Load Unit (refer to “Digital I/O" for details). The custom
card digital I/O is available in breakout area J50 (see
Figure 7-1).
