A test process measuring the phase modulation change of a phase modulated signal as the modulation rate frequency is changed from the referenced modulation rate frequency. The signal source is set up at a specified fixed carrier frequency, with a fixed deviation frequency then only the modulation rate frequency is changed from the reference rate frequency to the test rate frequency. The resulting values are measures as a dB change or % change.
Required Parameters

- LowPassFilter
- Detector
- UUT.Output – Output Name of the UUT Connecting Point
Output Value & Uncertainty
- dB – Measured Value – Reference Value
- % – Reference Value / Measured Value * 100
