4. FM Frequency Response
This automated test verifies the FM frequency response specifications. The equipment
measures the variations in frequency deviations due to changes in the applied FM rate; dc
to 100 kHz. The variations are expressed relative to a reference signal; 1 kHz rate set at
100 kHz deviation, in dB. Each frequency is tested with this 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 FM frequency response.
