PCS Receiver Check from RF to IQ

Use the following values to check the PCS receiver functionality from RF to IQ output.
1. Start Phoenix in Local Mode with only the Rx path turned on.
2. Inject a –75 dBm CW signal of 1960.5 MHz (i.e. 500 kHz offset from 1960 MHz
or 10 channels away).
3. Measure a 500 kHz tuning on the analyzer. You should see a typical -22 dBm IQ
tone for PCS. If the 300 kHz tone works but the 500 kHz tone does not, it is PCS
possible that the baseband filter was not set by Phoenix.
