Current Calibration
The Current Calibration test is similar to the Current Test for the charging algorithm in the factory
environment.
Note: For a correct and accurate result, perform the Battery Calibration Test before current
calibration. To perform this test you will need both channel 1 and 2 from the Power Supply.
Click 2. Current Calibration.
1.
Adjust channel 1 (the dummy battery) to 3.8 V.
2.
Click button SET VBATT to 3.8 Volt.
3.
Note the measured current for channel 2 (the customized charger with SEPI).
4.
Type in the measured current (in mA) in the text box.
5.
In this example the current is measured to 114 mA.
Press Enter.
6.
The phone will switch to charging with 800mA. Note the measured current value result at Power
7.
Supply Channel 2 DCIO/SEPI.
Type the new value in the text box.
8.
Press Enter.
9.
The test result (Passed or Failed) will now be displayed.
10.
When the measured values are within the limits the calibration will be passed otherwise the test will be
failed. The compensation factor will be calculated and stored in the GDFS.
More information about the test limits can be found in the product specific Troubleshooting Manual and
in the Read Limits Table in the Battery and Current Calibration Test document.
ADC Values
Select the desired ADC Channel.
1.
Click Read ADC value.
2.
- The measured value will be presented in both hex and decimal info boxes.
- N/A means that the General Purpose port is not used by this phone or this port is not supported by
ITP.
- If a port is missing in the Troubleshooting SW that port is not supported by the ITP SW.
SIM Card Control
This section controls the SIM interface in the phone.
SIM VCC: Voltage for the SIM Card will be activated.
SIM RESET, SIM DATA and SIM CLOCK: Activate the Reset, Data and Clock signals for the SIM Card.
SIM Com Test: Checks the communication with the SIM Card.
The test result (Passed or Failed) will be displayed in the info box.
Note: A SIM card must be inserted and a card reader connected to run this test.
APPENDIX Troubleshooting Software Documentation
Memory stick test checks the communication with the Memory stick card.
The test result (Passed
Note: A Memory stick card must be inserted and a Memory card reader connected to run this test.
End Calibration
Ends the calibration and no data will be stored.
Go Idle for 2 sec
The unit will be set to IDLE mode for 2 seconds.
Reboot Phone
IPT command KILL will be send and the phone will restart.
Radio Temperature
The value of the Radio Temperature will be displayed in the info box.
Display Temperature
The value of the Display Temperature will be displayed in the info box.
GPIO Manager Functions
Set GPIO port at Access and/or Application CPU to High or Low and Read Out status of the port.
MMI – Tab
Functions
Note: Some parts of MMI functions may not be possible to implement for all products due to
limitations in the ITP Software.
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.
Display Pattern
Activate different test patterns on the display.
LED and Backlight
Activate/Deactivate LEDs and Backlights on the phone.
Misc
Activate/Deactivate tests such as:
- Main Camera Test
- VGA Camera Test
