A test process measuring the deviation change of a frequency 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
- CarrierFrequency – RF Carrier Frequency

- Rate – Modulation Rate Frequency
Optional Parameters
- Power
- HiPassFilter
- LowPassFilter
- Detector
- UUT.Output – Output Name of the UUT Connecting Point
Output Value & Uncertainty
- dB – Measured Value – Reference Value
- % – Reference Value / Measured Value * 100
