Current Consumption Test
Step 1:
Insert Local SIM Card and use the phone with the Normal SW (SSW) and dummy battery connected
to Power Supply Channel 1 VBATT according to Picture 1.
Instrument settings: Voltage: 3.8 Volt, Limiter 3A.
Measure the current when Phone is off. Check the current consumption at Power Supply Channel 1
VBATT.
Picture 1
Current consumption in off mode should be less than 1mA.
If more than 1mA go to Dead Phone problems part 1 TRS guide.
Step 2:
Start the phone:
Measure the deep sleep current max 6mA typical between 0-3mA.
Make sure that the operator is running with deep sleep. (This operation can be switched off by
operator if the network is busy).
If phone using more than 6mA, then go to EMMA III and perform:
Software Update Contents Refresh (SUCR).
Step 3 with Mobile Phone Tester Instrument
Insert Test SIM Card and use the phone with the Normal SW (SSW) and dummy battery connected
to Power Supply Channel 1 VBATT according to Picture 1.
Instrument settings: Voltage: 3.8 Volt, Limiter 3A.
Use Mobile Phone Tester Instrument in signalling mode direct connected to the phone with RF
Connector or use Shield Box if not possible. Phone Display must be on during these tests to get
correct current measurements.
Perform Radio TX measurements at GSM and WCDMA Band by making the phone call from the UE
into the Mobile Phone Test Instrument (NW) and compare current consumption result with the test
limits below.
GSM 850, 900, 1800, 1900

Value (Reading 2).
Step3:
Compare the difference between Reading 1 and Reading 2 with the reference table below. If
the Reading 1 value is between 50 and 680 go to Interval 1, if between 681 and 800 go to
Interval 2, if between 801 and 880 go to Interval 3 and compare with the Reading 2 – Reading

Purpose with this test is to check following items:
- that ASIC-s Revision State is correct
- Check if communication to and from the ASIC-s is Ok
The tested ASIC-s is:
- D2000 (Anja)
- N2000 (Vera)

- N1200 (Gimli)
To perform this test use:
- Phone with the ITP SW
- TRS Fixture (On PBA Level)
- Dummy Battery (When TRS Fixture is not used)
- Power Supply Channel 1 VBATT (Voltage: 3.8V, Limiter: 2A)
- Power supply Channel 2 DCIO/SEPI (Voltage: 5V, Limiter: 2A)
- Fault Trace SW: General – Asic Revisions – Read All
Reference return value can be found in the table below.
TROUBLESHOOTING
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.

TROUBLESHOOTING Antenna Switch Test
Antenna Switch Test
The purpose of this test is to check antenna switch functionality controlled by CPU
(Central Processing Unit)
To perform this test use:
- Phone with the ITP SW
- TRS Fixture
- Fault Trace SW
SW Settings: According to Fault Trace SW Settings Instructions
- Power Supply Channel 1 VBATT
Instrument settings: 3.8 Volt, Limiter 3 A
- Power Supply Channel 2 DCIO/SEPI
Instrument settings: 5.0 Volt, Limiter 2 A
- DMM (Digital Multi Meter).
Test Instructions:
Use Fault Trace SW to switch between GSM 850, DCS 1800 and WCDMA BAND I.
Use DMM and measure voltage at MP 6 (C1240), MP 7 (C1241) and MP 8 (C1242).
Compare the result with Antenna Switch Reference Table.
