06.23.21 -- What You Need To Know About MIL-STD And TEMPEST Testing

This application note compares the measurement speed and level measurement accuracy of a conventional swept frequency spectrum analyzer against the speed and accuracy of advanced time domain scanning. It also contains guidance on making optimum use of time domain scans, plus their advantages in capturing intermittent signals with an improved POI.

The CS101 test defines the requirements between 30 Hz and 150 kHz for equipment and subsystems' alternating current (AC) below 30 Amps per phase and direct current (DC) input power leads. This test is used to increase the confidence that a device will be able to withstand signals coupled onto input power leads without malfunction or degradation of expected performance.

In most EMC radiated immunity testing applications, broadband amplifiers are required for generating the necessary field strengths. This article discusses the role of amplifiers in EMC testing, as well as the parameters and characteristics that have the greatest influence on amplifier performance.

In the field of TEMPEST, traditional analysis has focused on analog signal emanations from electronic devices. This article provides an overview on the digital demodulation basics and delivers an understanding on how to analyze impairments on digitally modulated signals.
