190 Keysight E8402A, E8404A C-Size Mainframes User and Service GuideProgramming the Enhanced Monitor SYSTem SubsystemSYSTem:NVSaveSYSTem:NVSave causes the enhanced monitor to store many of its parametersto non-volatile memory. This includes temperature limits, current limits, totalpower limits, status enable settings, PSC flag, beep frequency, beep duration,system name, mainframe serial number, and all RS-232 settings.Comments– Non-volatile memory has a finite access lifetime. For this reason, thesevalues are saved only when explicitly requested with this command and allat one time.
