Using the Multiplexer
Routing Relay
Operation
The Agilent E8462A uses eight Form C (C100 - C107) relays to route closed
channels to the appropriate terminal line (Ter0 to Ter15) dependent on the
FUNCtion mode set. A ninth Form C relay (C108) is used to switch terminal
lines to the analog bus. Figure 2-10 shows routing relays C100, C101 and
C102. These are three of the nine form C routing relays.
WIRE1 (1-wire) Example
In the 1-wire mode, all channels are routed to terminal line Ter0. Tree relays
T0 through T7 are closed to connect channels to either terminal line Ter0 or
Ter1. Tree relay T0 connects channels 0 - 15 to Ter0 and channels 32 - 47
to Ter1. Tree relay T1 connects channels 16 - 31 to Ter0 and channels 48 -
63 to Ter1. Tree relays T2 through T7 make similar connections to Ter0 and
Ter1. The routing relay C100 toggles between terminal lines Ter0 and Ter1
depending on the channel that is closed to route all channels to Ter0. When
you specify [ROUTe:]FUNCtion NONE, you are required to switch the
routing relays as required.
Function Mode Topologies
The following pages describe the topologies of the 12 modes you set with
the [ROUTe:]FUNCtion command. These tables list the bank and relay
associated with the channel of each mode. These are helpful when
programming the module using [ROUTe:]FUNCtion NONE and custom
configuring the 256 channels into a mixture of switching topologies. These
are also helpful when register programming the module.
