SENSe Subsystem
This command lets you choose one of two types of signal identification
methods when viewing multiple responses from non-preselected
external mixers.

[:SENSe]:SIDentify[:STATe] <boolean>
[:SENSe]:SIDentify[:STATe]?
This command activates an algorithm which either removes or aids
with the identification of multiple responses. These responses are
generated from a single input signal using non-preselected external
mixers.

Remarks:
Signal identification is not available with signal track, resolution
NOTE
bandwidths ≤300 Hz, demod, or averaging. Signal identification will be
turned off when input mixer is set to internal.

This function takes control of and uses Trace 1 and
Trace 2. Any data in these traces prior to activating
signal identification will be lost

ignal identification relies on the acquisition of data
from two successive sweeps. Therefore, if the analyzer
is in single sweep mode, two sweep triggers are needed
to generate the sweep pair. In image suppress mode,
synchronization is ensured by first turning off signal
identification, initiating a single sweep, then turning on
signal identification followed by two single sweeps.
To synchronize in image shift mode, turn off signal
identification, initiate a single sweep, and turn on
signal identification. The results of the first sweep after
signal identification is turned on must be ignored. The
data from the second sweep is available in Trace 1 and
the data from the third (shifted) sweep is available in
Trace 2.
