Susceptibility of Home Entertainment Equipment to High Power Interference
Measurements were conducted to define the suscep tibility of television and AM/FM receivers to high pow er electromagnetic fields. Fifty television receivers and twenty AM/FM receivers, representing different manufacturers, chassis configurations, and circuit fea tures, were subjected to pulsed UHF and S-band fields 2 2 at peak field strengths up to 38 dBm/m and 54 dBm/m , respectively. The susceptibility of the test specimen receivers was determined using the threshold of inter ference criterion, i.e., as that field strength which produced a detectable effect in receiver operation. Measurement results show that the average UHF and S-band interference thresholds for the test specimen television 2 2 receivers were approximately +30 dBm/m and +35 dBm/m , respectively. For the AM/FM receivers, the average UHF 2 and S-band thresholds were approximately +7 dBm/m and 2 +20 dBm/m , respectively. The interference thresholds for individual receivers varied as much as 40 dB between different samples.
