RF MS RX FER CELL CH384 At this stage, FER is most likely caused by a poor RF connection.

Perform a conductive RSSI measurement with sector power at -

65dBm (low LNA gain) and -100dBm (high LNA gain).

RF MS SINAD SINAD is measurement of a phone’s audio quality in an AMPS call.

Hence, a secured audio plug is needed to be checked for any con-

nection problem. Verify this on the bench in an AMPS call.

RF GPS Test Mode 3 Inject signal and test SNR with the GPS self-test. If SNR is out-of-

limits, then probe chain.

RF MS TX Limiting Po PCS CH25 Tx limiting power is most likely caused by a poor RF connection.

RF MS TX Limiting Po CELL CH1013 Tx limiting power is most likely caused by a poor RF connection.
