MEASUREMENT SETUP
Tuner FM
RF Generator
e.g. PM5326
Use a bandpass filter to eliminate hum(50Hz,100Hz) and disturbance from the pilottone(19kHz,38kHz).
Tuner AM (MW,LW)
RF Generator
e.g. PM5326
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 ).
CD
Use Audio Signal Disc SBC429 4822 397 30184
