Hello all,
Does anyone have information regarding the measurement parameters to be used in making Tuner performance measurements as per manufacturer spec’s. Just for instance:

• For FM Tuner distortion @65dBf 1kHz mono, what level of FM peak deviation is specified?
• For FM stereo measurements what is the 19kHz pilot level? 10% ?
• For FM stereo distortion measurements is the MPX generator set to L=R, or is only the channel under measurement (L or R) modulated?
• What is the measurement bandwidth specification? 50-15kHz?

These are just a few of several questions that came up this morning while measuring an FM tuner I just aligned for comparison to the manufacturer spec sheet. Changing any of the above settings changed the levels measured.

These are the kind of details that I need to sort out to make tuner measurements for publication. A reference or link to a published guideline would be awesome and most appreciated. I have not found such a guideline on-line so far. Thanks, Mike
