32-Pin Matrix Modules
Figure 6-2 shows the relay groupings for the Agilent E8792A.
(The Agilent E8793A is identical but does not have the
instrumentation relays.) Individual relays can be replaced on
the Agilent E8792A and E8793A 32-pin matrix modules. All
relays are 5V, 1A reed relays. The Agilent part number for an
8-pack of relays is 0490-1838.
The tables on the following pages list the component number for
each possible relay. The tables for the Measurement and
Instrument Matrices are listed in a row/column format. For
example, in
Table C-1 , the relay that connects Measurement
Matrix Row5 to Column3 (Abus3) is K305. Relay component
numbers are silk-screened on the back of the PC board.
