Introduction to RX troubleshooting

Rx can be tested by making a phone call or in the local mode. For the local mode testing, use Phoenix service
software.
The main Rx troubleshooting measurement is RSSI measurement. This test measures the signal strength of
the received signal. I and Q branches can be measured separately.
