MMEMory Subsystem - STATe and PREFerence Files
These MMEMory subsystem commands save and load instrument states (state files) and preferred settings for non-
volatile parameters (preference files). In general, state files store volatile settings associated with measurements.
Preferences are non-volatile parameters associated with the instrument, but not any specific measurement. The
following table summarizes what information is in each file.
