Overview Overview In many cases, it is imperative that the R&S NGM/NGL Power Supplies are used in a secured environment. Generally, these highly secured environments do not allow any test equipment to leave the area unless it can be proven that no user information leaves with the test equipment.
Operating Manual (NISPOM)", Chapter 8. Types of Memory and Information Storage The NGM/NGL Power Supplies contain various memory components. The following table provides an overview of the memory components that are part of your instrument. For a detailed description regarding type, size, usage and location, refer to the subsequent sections.
Sanitization procedure: Turn off instrument power SRAM The NGM/NGL series has up to four 32 KByte SRAM devices which are integrated in the power supply’s channel microcontrollers. The SRAMs contain the control and status/operating data of the channel control firmware and loses its memory as soon as power is removed.
Secure Erase Procedure 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.

Validity of instrument calibration after declassification The permanent adjustment values required to maintain the validity of the R&S NGM/NGL series’ calibration are not affected by the Secure Erase procedure. Therefore, performing the declassification procedure does not affect the validity of the instrument’s calibration.
