In precompliance and standards testing such as MIL-STD-461 and EN 55011 where a spectrum analyzer is used for measurements instead of an EMI receiver, it is always a good idea to use a transient limiter. The 11947A Transient limiter protects the spectrum analyzer input from damage caused by high-level transients from line impedance stabilization networks (LISNs) during EMI testing for conducted emissions.
