MEMory
The MEMory subsystem controls whether memory will be non-volatile and
determines the battery charge.

:BATTery[:STATe]
MEMory:BATTery[:STATe] <state> enables or disables non-volatile memory. If
state ON (1) is set, then measurement data will be preserved in the
HP E1429A’s internal memory when power fails or the instrument is turned off.
Note For data to be saved, MEMory:BATTery:STATe ON must be set before the
readings are taken (i.e. before the INITiate:IMMediate command is sent).

Comments • Executable when initiated: No
• Coupled Command: Yes. The state is coupled to the maximum trigger count.
• *RST Condition: not affected
• Power-On condition: The factory setting for MEMory:BATTery:STATe is OFF.
The battery state does not change at power-down or power-on.
• Enabling the battery abbreviates the power-on selt-test. A complete self-test is
executed with *TST?, which erases memory.
