Measurement Setup
Bandpass
250Hz-15kHz
e.g. 7122 707 48001 LF Voltmeter e.g. PM2534 DUT
RF Generator
e.g. PM5326
S/N and distortion meter e.g. Sound Technology ST1700B
Use a bandpass filter to eliminate hum (50Hz, 100Hz) and disturbance f\
rom the pilottone (19kHz, 38kHz).
Ri=50W
Tuner FM
Bandpass

S/N and distortion meter e.g. Sound Technology ST1700B
Frame aeriale.g. 7122 707 89001
Tuner AM (MW,LW)
To avoid atmospheric interference all AM-measurements have to be carried\
out in a Faraday´s cage.
