:EXTernal <list>

where; scanlist is the specified list of external channels (1 to 80) to be scanned.
:EXTernal?
Query programmed scan list
The Model 2002 can operate with an external switch system, such as the Keithley Model 7001
or 7002. The Model 2002 can measure up to 80 channels that are switched by the external
switching system. This command is used to define the external scan list for the Model 2002. See
paragraph 2.11 for details on scanning.
The scan list can contain 2 to 80 channels. See :SCAN[:INTernal] for examples to express a scan
list. The external scan by the Model 2002 is enabled by the ROUTe:SCAN:LSELect EXTernal
command.

Query functions for specified channels
These commands are used to assign measurement functions for internal channels (e.g. Model
2001 SCAN) or external channels. You can assign a unique measurement function to each chan-
nel. The function parameter specifies the measurement function for the channels specified by
the channel list (chanlist). See :CLOSe for examples to express a chanlist.
