Transmitter troubleshooting
General instructions for 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 Controls”; in WCDMA transmitter testing
the best tool is “TX Control”.
• Remember that re-tuning is not a fix! Phones are tuned correctly in production
