re:How do you check for transient noises & external interferences with a EMI receiver during emissions testing?Best Answer!
The first thing you can do is to perform a background or ambient scan with EUT/DUT turned off, this will give you an idea of the background noise. The EMI receiver has a Demodulator that is used to tune into a particular freq and check for AM/FM signals through the use of internal speakers. The AM/FM signals which are mostly radio stations can be heard through the speakers. The Demodulator is a great tool to verify the background noise level and ensure you're recording accurate emissions from EUT/DUT.
