9.3 Test set-up
The wanted test signal is supplied by generators G1,G2,G3 and G4, via the respective connections A or
V or S or T and the unwanted signal is supplied by generator G5. Network RCi matches the RF
disturbance source to the input impedance of the relevant audio terminal and a similar network Rco is
used to match the output terminals. Mains stop filter MSF is used to inject the unwanted signal at the
mains terminal and acts as a stop filter for unwanted signals from the mains network.
The equipment under test is placed 0.1m above the centre of a metal ground plane of dimensions 2m
by 1m. The mains lead shall be bundled to a length less than 0.3m and connected in the shortest
possible way to the mains stop filter MSF. The connection between the metal ground plane and the
shield of the RF cable at the audio input and output terminals shall be as short as possible.
The connecting cables are of the 50
Ω coaxial type.
The unwanted signal was amplitude modulated with 1kHz at 80% depth, supplied by generator G5.
