1 General

1.1 About This Document

This document contains the test requirements for a 3G GSM (900/1800/1900) and UMTS (2100) pocket transceiver using an antenna coupler (Radiated) or RF cable (Conducted) connection. These test sequences should be used as an arrival and verification test of radio functionality.

Tests are done in signaling mode, i.e. a call has been established to the test instrument. The test instrument controls the transceiver unit. RF performance is measured with an antenna coupler or the direct line connection, whichever method is selected.

1.2 Script Requirements

• The test should be designed so those users with little or no system expertise can perform accurate testing.

• The measurements should run automatically, though a certain amount of manual work is included (and mandatory), such as MS call setup (i.e. dialling number).

• It should be possible to print or store the measurement results.

• It should be possible to change the channels used in testing due to possible local

radio interference. The ranges for these settings are specified under the Channel Allocation Table.

• All functions and settings should be protected in such a manner that the end-user cannot directly change them. (For example, a password or encrypted settings file.)

• The attenuation factors that should be used are stated in section instrument must be capable of using different attenuation factors for RX and TX. It must also be possible to use various attenuation factors for different channels in each band.

NOTE! Any setups other than the one stated in this document must be

discussed and exempted by Sony Ericsson to be approved.

1.5 Test Limits

The test limits for each measurement are specified in the Sequence Tables.

1. Since a coupler introduces higher measurement inaccuracy, some measurements in the radiated test sequences may have wider limits than stated in the 3GPP specifications.

2. The conducted limits conform to the phase 3GPP specification.

1.6 Attenuation Factors

The different scripts must be configured with the correct attenuation factors and named after the product that they are designed to test. The attenuation factors to be used are stated in section

2.1.1 Sequence

1. Initialize instrument

2. Insert a test-USIM and attach a fully charged standard battery to the mobile. there is a high risk for incorrect test results.

3. Position the mobile in the coupler according to the picture.

It’s very important that a fully charged battery is used otherwise

4. Turn on the mobile and wait for registration.

5. Set up a call to the instrument or let the instrument call the MS.

6. Close the lid on the shielding box.

2.2 Audio Loopback

1. Set power level to high.

2. Activate audio loopback in the instrument.

3. Operator must acknowledge passed or failed before the test is continued.
