Customized Power Supply Channel 2 DCIO/SEPI Cable

To perform Current Calibration the phone must be supplied directly through the system connector. Customize the cable according to following instructions:

STEP 1:

Take the CST-75 battery charger and cut of the charger according to Picture 7.

Picture 7

Note: Cable length must be exact 1.3m.

STEP 2:

Connect the CST-75 charger Red or White wire to the Plus Output and the Black wire to the Minus (GND) Output at Power Supply Channel 2 DCIO/SEPI according to Picture 8.

STEP 4:

Connect DCIO and SEPI Interface Cable – A1 cables according to Picture 10.

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 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 directly 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.

The purpose of this test is to check the following items:

TROUBLESHOOTING

- Verify that the ASIC is correctly mounted, the communication works and that the revision is correct.

The tested ASICs are:

- D2000 (Anja)

- N2000 (Vera)

- N1400 (Bluetooth and FM Radio ASIC)

- N1200 (Thor)

- N1430 (A-GPS Module)

To perform this test use:

- Phone with 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 and go to: General – Asic Revisions – Read All

Power Supply Channel 1 VBATT must allow reverse current.

If the charging current is Not equal to the reference table go to Char ging problems TRS Guide.

If the charging current is equal to the reference table then insert the normal battery and test the charging current to verify that the phone battery is working properly.

Measure the voltage at the battery to check the current level. If the battery is receiving the right current, then the phone and the battery are working properly.
