Low noise amplifiers for EMC measurement applications
These pre-amplifiers are designed to amplify EMC interference signals received from antennas or LISNs or other ‘transducers’. They provide signal gain such that low level signals can be input to receiver such that their dynamic range is fully utilised.
SA1020
The SA1020 is a general purpose, battery powered amplifier particularly suited to radiated emission measurement applications covering the range 9KHz – 1GHz
P2085
The P2085 is a high gain amplifier, ideally suited to the recovery of LISN transient limiter insertion loss.
