HP FET MULTIPLEXER E1351A/53A manual ROUTe, ∙ Closing Channels To close

[ROUTe:]

The [ROUTe:] subsystem controls switching and scanning operations for the multiplexer modules in a switchbox.

Subsystem Syntax	[ROUTe:]
	CLOSe <channel_list>
	CLOSe? <channel_list>
	OPEN <channel_list>
	OPEN? <channel list>
	SCAN <channel_list>
	:MODE <mode>
	:MODE?
	:PORT <port>
	:PORT?
	SETTling
	[:TIME] <time>, <channel_list>
	[:TIME]? [MIN MAX] <channel_list>

CLOSe	[ROUTe:]CLOSe <channel_list> closes multiplexer channels specified in the
	channel list. The channel_list for CLOSe is in the form (@ccnn), or in special
	circumstances, (@ccnn,ccnn), where cc = card number (00-99) and nn = channel
	number (00-15). Before using the CLOSe command, you must specify the
	SCAN:MODE and SCAN:PORT, as these commands determine what switches
	will be closed for a given channel. You can only have one closed channel on a
	card at a time. If you want to close a channel on two different cards in the same
	VXIbus instrument (for example, 102,208) you can use (@ccnn,ccnn).
Parameters
	Parameter Name	Parameter Type	Range of Values
	channel_list	Numeric	cc00 - cc15
Comments	∙ Specify SCAN:MODE and SCAN:PORT: Before using the CLOSe
	command, specify the SCAN:MODE and SCAN:PORT.

∙Closing Channels: To close:

–use [ROUTe:]CLOSe (@ccnn) for a single channel;

–use [ROUTe:]CLOSe (@ccnn,ccnn) for single channels on different cards;

–use [ROUTe:]CLOSe (@ccnn,ccnn) for multiple channels;

–use [ROUTe:]CLOSe (@ccnn:ccnn) for sequential channels;

–use [ROUTe:]CLOSe (@ccnn:ccnn,ccnn:ccnn) for a group of sequential channels;

–or any combination.

Closure order for multiple channels with a single command is not guaranteed.

∙Related Commands: [ROUTe:]OPEN, [ROUTe:]CLOSe?, [ROUTe:]SCAN:MODE, [ROUTe:]SCAN:PORT

∙*RST Condition: All multiplexer channels are open.
