Declassification of National Instruments Arbitrary Waveform Generators and Function Generators
PrintOverview
This document is a letter of volatility discussing the declassification of National Instruments Arbitrary Waveform Generators and Function Generators. It describes both the volatile and non-volatile memory options of various devices. In addition, it details the purpose of each piece of memory and details the sanitation procedure for each. In general, the process for declassification is very simple. The volatile memory components on each of the boards will be cleared by a simple power down of the PC or PXI system. The non-volatile memory components will retain their contents when powered down. As a result, each of the tables below, list for each product, what is volatile and what is not volatile. It will also list memory size, its use, and whether the memory is accessible by a user.
Non-volatile memory accessibility with NI drivers
Non-volatile memory does allow for user accessibility except through our drivers. In most cases this is either for a) calibration b) memory configuration c) CPLDs d) Configuration ROM e) or other general EEPROMs. In all cases the non-volatile memory locations don’t have access to registries for dropping in classified information. Further, the memory values can’t be modified except through our specific hardware drivers for each different product.
PXI-5412 / PXI-5422 / PXI-5421 / PXI-5441
PXI-5402 / PXI-5406
PXI-5404
Conclusion
This document describes the declassification procedures for the national instruments signal generators product line. For more information on this product line, please visit http://www.ni.com/signalgenerators. In addition, note that the declassification procedures for an entire PXI system also require the sanitation of the PXI controller and chassis. This procedure can be found at the following link:
