1General
This document describes the process for functionally testing a mobile at the Electrical repair level.
Mobiles repaired at the Electrical repair level must have all Mechanical and Electrical level tests
performed and must pass without error to be considered a functional unit. If there are any failures,
repair the mobile according to the Mechanical and the Electrical Troubleshooting Guides.
2Test Preparations
2.1 RF Test Fixture (Conducted Test Method)
1. Remove the stylus, battery cover, camera cover and frame according to the Working
Instructions, Mechanical.
2. Peal down the antenna carefully according to pic 1.
3. Insert a test SIM, install a fully charged standard battery to the phone and start the phone.
NOTE! A Battery Eliminator (Dummy Battery) may be used in place of a standard fully
charged battery if you use a power supply that meets the requirements that are
documented in the Electrical Equipment List.
4. Attach the RF Probe to the mobile according to the pic 2.

3Go/No Go Test
This test verifies that the radio parameters of a mobile fulfil the GSM and WCDMA
specifications. A mobile is considered good if all measurements pass. All results will be
presented on the screen and can be printed out if a printer is available.
3.1 SERP GNG
NOTE! For complete and detailed user instructions, see the SERP Users Manual that gets
placed on the Desktop after SERP is installed.
1On a PC with SERP installed, start the SERP program by double clicking on the
“RepairManager.exe” icon on the desktop.
2Click on “Settings” in the SERP Window and verify that the test instrument and the GPIB
address correspond.
3Click on the “Station Setup” tab and verify that the “cable” (or the coupler) settings are
selected under the “RF Connection-GoNogo” Drop down window. Click on “Apply” and then
the “OK” button.
4Enter (or scan) the IMEI number of the mobile to be tested into the “Enter IMEI” box in the
SERP Window and click on the “Load” button. The appropriate phone model will be displayed.
5In the SERP window, check either the “GSM Calibration” or “WCDMA Calibration” box that
applies.
NOTE! Due to the sensitivity of the phone from outside interference during
WCDMA calibration, a Shield box and Service Tool Test Interface
setup are required for WCDMA Calibration. These can be also used for
GSM Calibration.
