Channel list parameter:
7702 <clist> = (@SCH)
where: S
CH = Switching module channel number (must be 2 digits)
7751/7752/7753 <clist> (DCV, Ω2, Ω4) = (@Mn) (see
* The <clist> parameter is used to configure one or more 7702 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 digit resolution,
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
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 7702 to select 4 digits when they are scanned.
FUNC 'RES' (@101:110)
RES:DIG 4.5,(@101:110)
