Letter of Volatility for Some FieldPoint or Compact FieldPoint Modules
Hardware: PXI/CompactPCI>>Controllers
Problem: I need official National Instruments confirmation that sensitive data passing through my static FieldPoint or Compact FieldPoint module will be erased when the device loses power. Where can I find it?
Solution: Here is a list of the current information on some of our FieldPoint and Compact FieldPoint modules. The list below contains the types of memory in each device, the amount, and whether or not the information stored in that memory is retained. Volatile memory loses its contents when the device is powered off, while nonvolatile memory retains its contents when the device is powered off.
