Ancilaries
The ease and effectiveness of conducted emission measurements can be enhanced by the use of appropriate filters. In particular, broadband noise below the frequencies of interest can cause limiting (compression) in spectrum analysers, distorting the measurements.
RF800 pass band filter covers the band B (150KHz - 30MHz), rejecting other frequencies. The pass band attenuation is only 2dB, but the key requirement to attenuate the strong low frequency noise often found in industrial sites exceeds 30dB.
The P2085 pre-amplifier delivers 30dB gain, flat between 9KHz and 30MHz. This covers bands A and B and is most useful when measuring low level conducted emissions. Note that this amplifier is included as standard with the CISPR16 LISNs supplied by Laplace.
