Troubleshooting With Testing And Tuning Tool; Manual Transmitter (Tx) Testing With Phoenix; General Instructions For Transmitter (Tx) Activation - Nokia RM-701 Service Manual

Note: The window appearance may differ depending on the
Tool versions.
RF Testing selection does all the same measurements as RF Tuning , but does not perform any tunings.
RF Testing is a safe way to check the basic cellular RF performance of the phone. The following test cases will
be performed (the complete set of measurements may differ depending on the data package content):
• GSM SNR
• GSM RSSI
• GSM / EDGE TX Power Level
• GSM Modulation & Switching spectrum
• GSM EDGE EVM
• GSM Burst Template
• GSM Phase Error
• WCDMA RSSI
• WCDMA SNR
• WCDMA TX Power Range
• WCDMA TX Max Output Power
• WCDMA ACP
• WCDMA EVM

Troubleshooting with Testing And Tuning Tool

Context
If limit fails occur while RF tests are performed with Testing And Tuning Tool, the user has to be very careful
to understand the measurement results. Fails may occur because of many reasons:
1 RF attenuation between the phone and the communication tester is something else as expected by the
Testing And Tuning Tool . Please check that cable, splitter and shield box selections are correct in the
Testing And Tuning Tool main window.
2 Test limits (specified in the product specific data package) are quite tight. Small limit violations do not
always mean that the tested product is broken, but the RF performance may not be as good as it should
be.
3 RX measurements (RSSI, SNR) may fail because of strong signals from base stations nearby. It is
recommended to always perform RF measurements in an RF-shielded environment (in an RF-shield box
or room).
4 The phone is really broken and needs more specific troubleshooting. Typical for these cases is that
Testing gives measurement results which are far from the test limits.

Manual transmitter (TX) testing with Phoenix

General instructions for transmitter (TX) activation

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"
