:LSELect? Query scan operation

This command is used to select and perform the desired scan operation. When INTernal is se-

lected, the Model 2002 scans the channels of the internal switching card according to how the

scan is conﬁgured (see :ROUTe:SCAN[:INTernal]). EXTernal is used to measure channels that

are controlled by an external switch system. When EXTernal is selected, the Model 2002 scans

the external scan list (see :SCAN:EXTernal).

With RATio or DELTa selected, the Model 2002 performs the appropriate math calculation us-

ing the speciﬁed reference channel and measure channel (see :RCHannel and :MCHannel).

The NONE selection disables all operations associated with a scan.
