Instrument Memory & Volatility
Volatile Memory
Volatile Memory
The PXB baseband generator and channel emulator also contains volatile memories. The volatile memories are not
battery backed-up. They do not retain any information when AC power is removed.
Removing power from this memory meets the memory sanitization requirements specified in the “Clearing and
Sanitization Matrix” in Section 5.2.5.5.5 of the ISFO Process Manual for the Certification and Accreditation of Classified
Systems under the NISPOM .
