6 Using the Pin Matrix Cards
Using the 64-Pin Matrix Cards
Conceptual Overview
The Agilent E8782A Pin Matrix contains 40 x 4 Measurement
Matrix for switching signals to and from the Analog Bus. It also
contains a 24 x 5 Instrument Matrix that connects external
measuring instruments to the Analog Bus. The E8783A Pin
Matrix Modules contain only a 64 x 4 Measurement Matrix for
switching signals to and from the Analog Bus. Figure 6-11 is a
simplified block diagram showing how the Agilent E8782A and
E8783A are typically used together in a system. As shown in
Figure 6-11, if you need more UUT connections, simply add
more Agilent E8783A Pin Matrix Cards to the bus.
