HP E1368A manual ∙ Opening Channels To open, Example Opening Microwave Switch Channels

Page 59

CLOSe? [ROUTe:]CLOSe? <channel_list> returns the current state of the channel(s) queried. The channel_list is in the form (@ccnn). The command returns 1 if the channel is closed or returns 0 if the channel is open.

Comments ∙ Query is Software Readback: The [ROUTe:]CLOSe? command returns the current software state of the channel specified. It does not account for relay hardware failures. A maximum of 127 channels at a time can be queried for a multi-module switchbox.

Example Query Channel Closure

This example closes channels 100 and 202 of a two-module switchbox (card numbers 01 and 02) and queries channel closure. Since the channels are programmed to be closed 1,1 is returned.

CLOS	(@100,202)	100 closes channel 00 of card #1;
		202 closes channel 02 of card #2.
CLOS?	(@202)	Query channel 02 of card #2.

OPEN [ROUTe:]OPEN <channel_list> opens the Microwave Switch channels specified in the channel_list. The channel_list is in the form (@ccnn) where cc = card number (00-99) and nn = channel number (00-04).

Parameters

	Parameter Name	Parameter Type	Range of Values	Default Value

	channel_list	numeric	cc00 - cc04	N/A


Comments	∙ Opening Channels: To open:

–a single channel, use [ROUTe:]OPEN (@ccnn);

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

–sequential channels, use [ROUTe:]OPEN (@ccnn:ccnn);

–a group of sequential channels, use

[ROUTe:]OPEN (@ccnn:ccnn,ccnn:ccnn);

–or any combination.

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

∙Related Commands: [ROUTe:]CLOSe, [ROUTe:]OPEN?

∙*RST Condition: All channels are open.

Example Opening Microwave Switch Channels

This example opens channel 00 of a card number #1 and channel 02 of a card number #2 in a two-module switchbox.

OPEN (@100,202)	100 opens channel 00 of card #1;
	202 opens channel 02 of card #2
