5. AM Frequency Response
This automated test verifies the AM frequency response specifications. The equipment
measures the variations in modulation depth due to changes in the applied AM rate; dc to
10 kHz. The response is relative to a 1 kHz rate set at the test depth, and expressed in dB.
Each frequency is tested with the following sequence:
1. A reference signal is measured.
2. The set depth is measured for each applied rate change.
3. Each depth measurement is compared to the reference signal depth.
The comparison is a calculation of the difference in the depths relative to the reference
rate. The relative value is the AM Frequency Response.
