NGM/NGL
Channel MCU Flash
The NGM/NGL series has up to four microcontrollers each with an integrated 256
KByte flash memory with 3 KByte Boot Flash. The flash memory contains the channel
control firmware as well as calibration data. It does not hold user data nor can the user
access the storage.
Sanitization procedure: None required (no user data)
EEPROM
The R&S NGM/NGL series has one 32Kbit EEPROM used to store production and
calibration data.
Sanitization procedure: None required (no user data)
Secure Erase Procedure
To sanitize the internal flash memory, perform the following steps:
1.
2.
3.
4.
5.
Do not turn off the instrument during the Secure Erase process!
The Secure Erase procedure meets the memory sanitization requirements specified in
the "Clearing and Sanitization Matrix" in Section 14.1.16 of the ISFO Process Manual
for the Certification and Accreditation of Classified Systems under the NISPOM.
Instrument Declassification
Before you can remove the Power Supply from a secured area (for example to perform
service or calibration), all classified user data needs to be removed. You can declassify
the Power Supply as follows:
1.
2.
Following these steps removes all user data from the Power Supply. The Power
Supply can now leave the secured area. These declassification procedures meet the
needs of customers working in secured areas.
