:CALibrate:OPTical:USER:CHANnel:STATus:TIME?
Query Syntax
:CALibrate:OPTical:USER:CHANnel{1:8}{A|B|C|D}:STATus:TIME?
Where the required specifier {1:8}{A|B|C|D}
identifies a channel by its module slot number and channel letter. For example, channel 3C (CHANnel3C
).
The channel specifier will fail if it does not include a slot number. If instead the suffix's channel letter is missing, the command defaults to letter A
. As a result, the best practice is to always explicitly specify the channel by including both the module slot number and channel letter.
