MEASUREMENT SETUP
Tuner FM
RF Generator
e.g. PM5326
Use a bandp ass filter to eliminate hum (50Hz,100H z) and distu rbance from the pilottone(19kHz,38k Hz).
Tuner A M (MW,LW)
RF G enerator
e.g. PM53 26
To a void atmosp heric interfer ence all AM- measurements have to b e carried out in a Faraday s cage.
Use a bandpass filter ( or at le ast a high pass filter with 250Hz) to eliminate hum ( 50Hz,100H z ).
