Steps
1. Place the phone into the AMS coupler jig, establish a call and set the path loss using the above attenuation
TX.
2. Check the report power level for the UE. If it is not in the target range, e.g. 31.7+/-4.5dB (31.7-4.5 to 31.7
+4.5) for 850 TX, it may indicate that one of the antenna pogo pins may not contact to the PWB.
3. Replace the antenna.
4. Repeat steps 2 and 3. If the power level is within the target range, the replaced antenna was broken;
otherwise, other RF part might not function properly. In this case RF troubleshooting should be carried
out.
