Summary of Memory Declassification Procedures
This section explains how to clear, sanitize, and remove memory from your instrument, for all
classes of memory that are writeable during normal operation and for which the clearing and
sanitization procedure is more than trivial such as rebooting your instrument.
Before beginning clearing or sanitization, be sure to write down and save the instrument’s
Model, Serial number, Option, and software License Key information. Read this entire
document before using any sanitization procedure. Failure to do so may necessitate
returning the instrument to an Authorized Keysight Service Center for firmware downloads
and recalibration.

Memory sanitization
On the remote interface send: SYSTem:SECurity:IMMediate
This procedure clears all instrument memory except for the instrument’s firmware, MAC
address and serial number and calibration data, and then reboots the instrument to the
new memory state. This routine writes all zeros to memory and then performs a full chip
erase as per manufacturer’s data sheet. This procedure is not recommended for use in
routine applications because of the possibility of unintended loss of data.
