Channel list parameter (7702):
<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
Channel list parameter (7751/7752/7753 using memory patterns):
<clist> = (@Mn)
where: M
= Memory pattern command
n
= Memory location number (1 to 40)
Examples:
(@M1) = Memory location #1
(@M3) = Memory location #3
Notes:
1. Not affected by *RST and SYSTem:PRESet. Front panel factory default is OFF.
2. *RST sets count to 1 and SYSTem:PRESet sets count to INFinity.
3. The default value depends on which switching module is installed.

in the order that they are listed. The following example shows the proper format for
specifying channels in a scan list for a sequential scan:
