convenience, eliminating the need for using disk files when saving and
recalling instrument states.

Since *LRN?, by IEEE definition, only contains the actual instrument state,
exclusive of data traces and calibration arrays, the network analyzer provides
the command
This command saves the data traces and calibration arrays if they are
enabled under
SCPI commands. Using the *LRN command to set the instrument settings
takes about the same amount of time as recalling a file from disk using -
MMEM:LOAD:STATe.
