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 spe-
cific measurement. The following table summarizes what information is in each file.
