Test Instruction Repair, Electrical

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 / 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.

There are two options available for performing the GNG test, SERP GNG or a Stand alone GNG. The SERP GNG can be downloaded from CSPN as described in Installation Instructions, Electrical (1215-7373). To perform a Stand alone GNG a test script must be written in accordance with the GO/NO GO Test Script Specification, Electrical (1215-7380) located on CSPN.

2.1 Go/No-Go Test Preparations

2.1.1 RF Probe (Conducted Test Method)

1. Disassembly the phone from 2.1.1 - 2.1.6 and 2.1.8 according to Working Instructions, Mechanical (1215-7363). Replace the Main Keyboard and the Front cover with the Navigation Keyboard.

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.

2.1.2 RF Coupler (Radiated Test Method)

1. Insert a test SIM that is compatible with your Test Instrument 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 phone on the Grid Positioning plate in the coupler as shown with the reference point at E14 for W595 and W595s or A17 for W595a and W595c. Additional information on the Grid Positioning plate and other supported SEMC phones 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.
