Charging Test
To perform this test use:
- Phone with the Normal SW (SSW)
- Dummy Battery connected to Power Supply Channel 1 VBATT
- Power Supply Channel 1 VBATT instrument settings:
Voltage: 3.0 to 4.2 Volts, according to VBATT row in the Reference Table.
Limiter: 2A
- Power Supply Channel 2 DCIO/SEPI instrument settings:
Voltage: 5V
Limiter: 2A
Test instructions:
- Disconnect the DCIO/SEPI Cable between each measurement and wait for phone to
shut down when changing VBATT voltage.
- Take a note of Current measurements at Power Supply Channel 2 DCIO/SEPI and
Display charging indicator status, X seconds after DCIO/SEPI cable has been inserted
according to Test Time row in the reference table below.
- Compare test results with the reference table below, tolerance +/-20%.

Power Supply Channel 1 VBATT must allow
reverse current.
If the charging current is Not equal to the reference table go to Charging problems TRS
Guide.
If the charging current is equal to reference table then insert the normal battery and test the
charging current to define if the phone battery is working properly.
Measure the voltage at the battery to define the current level.
If the battery is receiving the right current, then the phone and the battery are working
properly.

K630 - V640 - K660
ASIC Revision Test
The purpose with this test is to check following items:
- that the ASICs Revision State is correct
- Check if communication to and from the ASIC-s is Ok
The following ASICs are tested:
- D2000 (Anja)
- N2000 (Vera)
- N1400 (Bluetooth and FM Radio ASIC)
To perform this test use:
- Phone with the ITP SW
- TRS Fixture
- Power Supply Channel 1 VBATT (Voltage: 3.8V, Limiter: 2A)
- Power supply Channel 2 DCIO/SEPI (Voltage: 5V, Limiter: 2A)
- Fault Trace SW choose General – Asic Revisions – Read All
Reference return value can be found in the table below.
