1 General
This document describes the test procedures for the electrical repair package.
2 Go/No-Go Test
This test verifies that the radio parameters of a mobile fulfil the GSM 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.
There are two options available for performing the GNG test, SERP GNG or a Stand
alone GNG.
There are two methods of running a Stand alone GNG test. The first is to use a script
provided by Sony Ericsson for the Willtek 4202 which can be downloaded from
CSPN as described in Installation Instructions, Electrical. The second is to write a
script in accordance with the GO/NO GO Test Script Specification, Electrical which is
located on CSPN.

2.1 Go/No-Go Test Preparations
2.1.1 RF Test Fixture (Conducted Test Method)
1. Remove the back cover according to Working Instructions, Mechanical.
2. Insert a test SIM that is compatible with your Test Instrument and install a fully
charged standard battery to the mobile.
NOTE! A 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.
3. Install the RF Probe in the RF Holder and attach to the mobile according to the
picture.

2.1.2 RF Coupler (Radiated Test Method)
1. Insert a test SIM and a fully charged standard battery. It is very important that a
standard fully charged battery is used; otherwise, there is a risk for wrong test
results.
2. Position the handset on the Grid Positioning plate in the coupler as shown with
the Reference point at I9. Additional information on the Grid Positioning plate and
other supported SEMC handsets that utilize the Grid Positioning plate, is
available in “SERPINFO.htm - R&S Grid plate for SERP” which is located on the
windows desktop after SERP is installed.
NOTE! THE GRID POSITION IS APPLICABLE FOR BOTH W380 AND Z555

3 Calibration
The Calibration Program in SERP should only be run as directed by the Electrical
Troubleshooting Guide or the Electrical Parts List.
NOTE! A TEST PROGRAM MUST BE LOADED IN THE HANDSET BEFORE
PERFORMING THE CALIBRATION ROUTINE. AFTER
CALIBRATION THE HANDSETS MUST BE RE-CUSTOMIZED WITH
SIGNALLING SW.
