Channel list parameter:
<clist> = (@SCH)
where: S = Mainframe slot number (1 or 2)
CH = Switching module channel number (must be 2 digits)
Examples: (@101) = Slot 1, Channel 1
(@101, 203) = Slot 1, Channel 1 and Slot 2, Channel 3
(@101:110) = Slot 1, Channels 1 through 10
* The <clist> parameter is used to configure one or more channels for a scan. Each channel in the <clist> must be set to the function
specified by the rel (reference) command. If not, a conflict error (-221) will occur. For example, UNITs:VOLTage:AC dB, (@101)
is only valid if scan channel 101 is set for the ACV function.
