Description
The information received from the spectrum analyzer is called the learn string. The learn string
can be sent from the controller back to the spectrum analyzer to restore the spectrum analyzer
to its original state.
The learn string requires 202 bytes of storage space. See “Saving and Recalling Instrument
States,
n
in Chapter 3 for more information.
To restore the spectrum analyzer to the learn string state, you must return the learn string to
the spectrum analyzer. The learn string contains information to tell the spectrum analyzer that
it is learn string data. (Also see “RCLS” and “SAVES.“)
