Example:

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).

Channels

Comments

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.
