Closing VSA and/or VSB Tree Relays: Closing tree relays VSA and/or VSB
is typically required for most uses of this multiplexer. This connects channels
to the voltage sense lines of the analog bus. See "Figure 3-1. HP E1476A
Multplexer Module Status System" on page 82 for VSA and VSB connections
to the analog bus.
•
Closing the CS Tree Relay: Closing the CS tree relay connects channels in
bank B to the current source lines of the analog bus. This is required for four-
wire measurements.

Closing Multiplexer Channels
This example closes channel 00 of a card number 1 Multiplexer Module and channel
15 of a card number 2 Multiplexer Module in a single switchbox.

queried. Channel_list is in the form (@ccnn). The command returns "1" if the
channel is closed or returns "0" if the channel is open. If a list of channels is queried,
a comma delineated list of 0 or 1 values is returned in the same order of the channel
list.

Query is Software Readback: The
current state of the hardware controlling the specified channel. It does not
account for a failed switch element or a relay closed by direct register access
(see Appendix B).
