Immunity testing with a Tekbox TEM cell

September 27, 2018

Tekbox put together a nice application note on immunity testing using a TEM cell and a SIGLENT SSA3000X spectrum analyzer. TEM cells are specialized hardware enclosures that can provide high electric fields and also do offer some shielding from environmental RF. If you are having immunity issues, this note may provide some helpful information and guidance. … Continued

Attenuator verification using a spectrum analyzer with a tracking generator

September 7, 2018

Attenuators are elements of an electrical circuit that are used to decrease the amount of power delivered to the next stage of the circuit. An ideal attenuator would have a flat frequency response, that is, it would decrease the amplitude of all input signals equally, regardless of the frequency. In this note, we are going to … Continued
