6. Phase Modulation Frequency Response
This automated test verifies the phase modulation frequency response specifications. The
equipment measures the variations in phase deviations due to changes in the applied
Φ
M rate; dc to 100 kHz. The response is relative to a 1 kHz reference at the same phase
deviation, and expressed in dB. Each frequency is tested with the following sequence:
1. A reference signal is measured.
2. The set deviation is measured for each applied rate change.
3. Each deviation measurement is compared to the reference signal deviation.
The comparison is a calculation of the difference in the deviations relative to the reference
rate. The relative value is the
Φ
M frequency response.
