IEEE-488 Reference
4-100
The scan list can contain 2 to 80 channels. The following examples demonstrate the various
forms for expressing a scan list:
List = (@ 2,4,6) Channels separated by commas (,).
= (@ 1:8) Range of channels (1 though 8). Range limits separated by a colon (:).
= (@ 1:5,7) Range entry and single entry separated by a comma.
Before performing an external scan, be sure that the Model 2001 is appropriately configured for
the measurements. The :SCAN[:INTernal]:FUNCtion command can be used to set each channel
for a specific measurement function. Also, if you want the instrument to perform a particular
number of scans, make sure to configure the Trigger Model appropriately (see Trigger sub-
system).
The external scan by the Model 2001 is enabled by the ROUTe:SCAN:LSELect EXTernal com-
mand.
Programming example OUTPUT 716; “:rout:scan:ext (@ 1:40)” ! Define external scan list (1-40).
:FUNCtion <list>, <name>
:ROUTe:SCAN[:INTernal]:FUNCtion <list>, <name> Assign functions to channels; Internal
:ROUTe:SCAN:EXTernal:FUNCtion <list>, <name> Assign functions to channels; External
Parameter <list> = (@ chanlist)
where; chanlist is the specified list of channels:
1 to 10 for Internal
1 to 80 for External
<name> = ‘NONE’
= ‘VOLTage:DC’
= ‘VOLTage:AC’
= ‘TEMPerature’
= ‘FREQuency’
= ‘RESistance’
= ‘FRESistance’
= ‘RJUNctionX’ where; X = 1 to 5
= ‘ALTernate[1]’
= ‘CURRent:DC’ (External only)
= ‘CURRent:AC’ (External only)
Formats :rout:scan:func <list>, <name>
:rout:scan:ext:func <list>, <name>
Defaults Power-up Saved power-on setup
*RST VOLTage:DC (all channels)
:SYSTem:PRESet VOLTage:DC (all channels)
