Matrix-Type
Switching
This example connects channel 13 to channel 01 of an RF multiplexer in
matrix-type configuration. The multiplexer is defined as a single-module
switchbox instrument. See the following figure for typical user
connections.
To connect channel 13 to channel 01, execute:
CLOS (@101,113)
! Connect channel 01 to channel 13.
1 is the card number and 01, 13
are channel numbers.
To open the channels, use
OPEN (@101,113)
.

Query Channel States. Use
CLOSe? <
channel_list
>
or
OPEN? <
channel_list
>
to query the channel states (open/closed).
CLOSe?
returns a 1 for channels closed, 0 for channels open.
OPEN?
returns a 0 for
channels closed, 1 for channels open. (Commands do not account for relay
hardware failures.)
Channel Closure Order.
CLOSe <
channel_list
>
can be used to close
multiple channels (one at a time). However, the sequence in which multiple
channels are closed with a single command is not guaranteed.
