Channel
List
One or more channels (only for the
multiplexer channels), the rules are as
follows:
(@101): channel 01 on the module in Slot1;
(@101:103): channel 01 through 03 on the
module in Slot1;
(@101:103,301,406:408): channel 01
through 03 on the module in Slot1, channel
01 on the module in Slot3 and channel 06
through 08 on the module in Slot4.
If the parameter
is omitted, this
command will be
applied to the
whole scan list.
Explanation  When enabled, channel n (n ranges from 1 to 16 for MC3132 and MC3232 and ranges
from 1 to 10 for MC3324 and MC3120) is paired with channel n+16 (MC3132 and
MC3232) or n+10 (MC3324 and MC3120) automatically. Channel n is used to connect
the source terminal of the DMM module and channel n+16 or channel n+10 is used to
connect the sense terminal of the DMM module. Other related configurations are not
allowed for the paired channels of the 4-wire mode.
 The MC3164 and MC3264 modules do not support the 4-wire scan.
 This command is valid only when the DMM module is disabled (refer to the
INSTrument:DMM command) or is not installed.
 The
ROUTe:CLOSe, ROUTe:CLOSe:EXCLusive, and ROUTe:OPEN commands ignore the
current ROUTe:CHANnel:FWIRe setting (when no channel is in the scan list).
Return
Format
The query returns 0 (OFF) or 1 (ON). Multiple return values are separated by commas.
Example
INST:DMM OFF
ROUT:CHAN:FWIR ON,(@201:203)
ROUT:CHAN:FWIR? (@201:203)
The query returns 1,1,1.
