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 digits command. If not, a conflict error (-221) will occur. For example, VOLTage:AC:DIGits 4.5, (@101) is only
valid if scan channel 101 is set for the ACV function.
Setting digits
Even though the parameters for the DIGits command are expressed as integers (4 to 7),
you can specify resolution using a real number. For example, to select 3
let <n> = 3.5. Internally the instrument rounds the entered parameter value to the nearest
integer.
As implied by the commands in
own unique digits setting.
Digits programming examples
NOTE
Example #1 — The following commands set digits for DCV and ACI:
VOLT:DIG 5.5
CURR:AC:DIG 4
Example #2 — The following command sequence configures channels 101 through 110 of
the Model 7700 to select 4
FUNC 'RES', (@101:110)
RES:DIG 4.5,(@101:110)
Optional root command.
The following examples can be run from the KE2700 Instrument Driver using
the example named "Digits" in
digits when they are scanned.
