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.

2.1.2 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.

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.
