Internal FM Accuracy and Distortion

Internal FM Accuracy and Distortion

These automated tests verify the FM accuracy and distortion specifications. Accuracy is verified directly with

a measuring receiver, and distortion is verified by measuring the demodulated output of the measuring

receiver, using the audio analyzer. The audio analyzer provides a more accurate verification with better

resolution, as opposed to the measuring receiver alone.

Recommended Equipment

• Agilent 8902A measuring receiver

• Agilent 8903B audio analyzer with Options 010 and 051, or Options 011 and 050
