SERVICE MEASUREMENT
2 - 2
Tuner SW
RF Generator
e.g. PM5326
Aerial replacement
DUT
Capacitor
Ri=50Ω
R=50Ω
Bandpass
250Hz-15kHz
e.g. 7122 707 48001
LF Voltmeter
e.g. PM2534
S/N and distortion meter
e.g. Sound Technology ST1700B
To avoid atmospheric interference all AM-measurements have to be carried out in a Faraday«s cage.
Use a bandpass filter (or at least a high pass filter with 250Hz) to eliminate hum (50Hz, 100Hz).
