Transmitter troubleshooting
Introduction to transmitter (TX) troubleshooting
Please note the following before performing transmitter tests:
TX troubleshooting requires TX operation.
Do not transmit on frequencies that are in use!
The transmitter can be controlled in local mode for diagnostic purposes.
The most useful Phoenix tool for GSM transmitter testing is “RF Control”; in WCDMA transmitter testing
the best tool is “TX Control”.
Remember that re-tuning is not a fix! Phones are tuned correctly in production.
The TX path for GSM and WCDMA are using the same filters in some bands. Please refer to RF component
reference (page 4–25) for details.
Note: Never activate the GSM or WCDMA transmitter without a proper antenna load. Always connect
a 50Ω load to the RF connector (antenna, RF-measurement equipment or at least a 2W dummy load);
otherwise the GSM or WCDMA Power amplifier (PA) may be damaged.
