Troubleshooting Software Documentation
Introduction
Using this software you can control most parts and functions of all Sony Ericsson mobile phones. It is a
GUI (Graphical User Interface) for the commands implemented in the ITP (Integrated Test Program).
The software communicates with the phone through standard serial communication over a USB/RS232
interface (SEPI).
Note: The Troubleshooting Software application is to be used with the Troubleshooting Manual and the
Troubleshooting fixture kit.
The functions in the Troubleshooting Software application are divided into three main sections:
Communication Settings, Radio Control and Base Band Controls. These main sections are
presented under six different tabs.
All settings and functions are collected under these six main tabs.
Communication Settings
All settings for the communication between the Troubleshooting Software application and the phone
are presented under the Communication Settings Tab.
Radio Controls
Note: Some parts of Radio Control functions may not be implemented since they are not supported by
the ITP SW.
Note: There are some differences in the user interface depending on the phone project file loaded.
Some functions may not be available on all products.
All Radio Control Functions implemented in the Troubleshooting Software are presented under the Tx
and Rx tab. The main radio functions of the mobile phone presented in this tab are:
x
GSM radio part
x
WCDMA radio part
x
Bluetooth radio part
In the GSM and the WCDMA radio control part the following radio functions can be controlled:
Transmitter (TX) and Receiver (RX)
In the Bluetooth radio control part only the Transmitter (TX) function is supported.
Base Band Controls
Note: Some parts of Base Band Control functions may not be implemented since they are not
supported by the ITP SW.
Note: There are some differences in the user interface depending on the phone project file loaded.
Some functions may not be available for all products.
The functions for Base Band Control are presented under the following four different tabs:
