AMPS Receiver Check from RF to IQ
Use the following steps to check the AMPS receiver functionality from RF to IQ output.
1. Start Phoenix in Local Mode with only the RX path turned on.
2. Inject a –75dBm CW signal of 881.53MHz (i.e., 10kHz offset from 881.52MHz)
into the RF.
3. Measure a 10kHz tone on the analyzer. You should see a typical -20Bm IQ
tuning for AMPS.
