SYSTem:SECurity:IMMediate
Clears all user memory and reboots the instrument. This command is typically used to prepare the
instrument for removal from a secure area. It sanitizes all user data. It writes all zeros to flash memory
and then performs a chip erase as per manufacturer's data sheet. Identification data (instrument
firmware, model number, serial number, MAC address and calibration data) is not erased. After the
data is cleared, the instrument is rebooted.
This procedure is not recommended for use in routine applications because of the possibility of
unintended loss of data.
Parameter Typical Return
(none) (none)
Sanitizes the instrument: SYST:SEC:IMM
SYSTem:SET <block data>
SYSTem:SET?
Get and set the instrument state. The query form of the command returns a definite length block that
contains the instrument state. This block data can be sent back to the instrument to restore it to the
state in the block.
