Phase Modulation Accuracy and Distortion

Phase Modulation Accuracy and Distortion

These automated tests verify the phase modulation accuracy and distortion specifications. Accuracy is

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

from the measuring receiver, using the audio analyzer. The audio analyzer provides a more accurate

verification with better resolution than using the measuring receiver alone.

Recommended Equipment

• Agilent 8902A measuring receiver

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