Using the 32-Pin Matrix Cards
Conceptual Overview
Both the Agilent E8792A and E8793A 32-Pin Matrix Modules
contain a 32 x 4 Measurement Matrix for switching signals to
and from the Analog Bus. The Agilent E8792A also contains a 16
x 5 Instrument Matrix that connects external measuring
instruments to the Analog Bus. Figure 6-1 is a simplified block
diagram showing how the Agilent E8792A and E8793A are
typically used together in a system. As shown in Figure 6-1, if
you need more UUT connections, simply add more Agilent
E8793A 32-Pin Matrix Cards to the bus.
Features
Key features of the cards include:
• 16 x 5 high-speed reed relay Instrument Matrix (Agilent
E8793A only),
• 32 x 4 high-speed reed relay Measurement Matrix,
• An integrated relay timer,
