•
Channel elements have the form ccnn, where cc = card number (01) and nn =
channel number (00 - 15). Since the SCPI driver does not support multiple
cards you can omit the card number and specify only the channel number. To
be consistent with other HP Switch modules it is permissible to specify a card
number of 1.
•
To query a single channel, use [ROUTe]:CLOSe? (@ nn); for multiple
channels use [ROUTe]:CLOSe? (@ nn, nn, ...); for sequential channel, use
[ROUTe]:CLOSe? (@ nn:nn); for groups of sequential channels, use
[ROUTe]:CLOSe? (@ nn:nn, nn:nn); or any combination.
•
The instrument driver returns a 1 or 0 for each channel in the list, in the same
order that the list was specified. A response of 1 means the channel is closed
and a 0 means the channel is open. Note: The response of the
[ROUTe]:CLOSe? query is the opposite of [ROUTe]:OPEN? query.
Refer to the [ROUTe]:CLOSe command for a list of common error conditions
related to channel lists. Error numbers and corresponding error messages can be
found using SYSTem:ERRor? query.
CLOS? (@00,03)
The [ROUTe]:OPEN command opens the channels specified in the channel list.
