Fig.5 Set-up for CENELEC EN 55020 passive interference measurements.
SG1: Wanted carrier; modulated with f = 1 kHz,
f =
±
40 kHz (for audio reference)
SG2: Unwanted carrier; modulated with f = 1 kHz, FM:
f =
±
40 kHz (in band) or AM: m = 80% (out of band)
increase level of SG2 until S/N = 26 dB w.r.t. wanted modulation (for car radio, home radio S/N = 40 dB)
