Control of media
Another option to secure sensitive information is to keep physical media within the
classified area, see
[1], paragraph 4.4.
Volatile memory
"Memory components that do not retain data after removal of all electrical power sour-
ces, and when reinserted into a similarly configured system, are considered volatile
memory components."
[2]
The volatile memory in the instrument does not have battery backup. It loses its con-
tents when power is removed from the instrument.
If the instrument is battery operated, e.g. handhelds, it retains data in the volatile mem-
ory as long as the battery is installed.
Typical examples are RAM, e.g. SDRAM.
Non-volatile memory
"Components that retain data when all power sources are discontinued are non-volatile
memory components."
[2].
In the context of this document, non-volatile memory components are non-user acces-
sible internal memory types, e.g. EEPROM, Flash, etc.
Media
Media are types of non-volatile memory components. In the context of this document,
media are user-accessible and retain data when you turn off power.
Media types are Hard Disk Drives (
HDD), Solid State Drives (SSD), Memory Cards,
e.g.
SD, microSD, CFast, etc., USB removable media, e.g. Pen Drives, Memory Sticks,
Thumb Drives, etc. and similar technologies.
4 Statement of volatility
The R&S FPL1000 contains various memory components. See the subsequent sec-
tions for a detailed description regarding type, size, usage and location.
Notes on memory sizes
Due to the continuous development of memory components, the listed values of mem-
ory sizes may not represent the current, but the minimal configuration.
