:CALibrate:FRAMe:TIMebase:USER:CHANnel
Command Syntax
:CALibrate:FRAMe:TIMebase:USER:CHANnel CHAN{1:4}{A|B|C|D}
Where the required specifier {1:4}{A|B|C|D} identifies a channel by its module slot number and channel letter. For example, channel 3C (CHAN3C).
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.
