1.1 About This Document

This document contains the test requirements for a GSM Tri-band (900/1800/1900) pocket
transceiver for use with an antenna coupler or RF fixture. 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
a RF fixture, 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. dialing 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 4. The test 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

approved by Sony Ericsson.

1.3 Channel Allocation Table

Band Ch definition Any ARFCN of:
GSM900 Low 975-979
GSM900 Mid 36-40
GSM900 High 120-124

GSM 1800 Low 512-517
GSM 1800 Mid 697-702
GSM 1800 High 880-885

GSM1900 Low 512-517
GSM1900 Mid 658-663
GSM1900 High 805-810

1.4 Power Level Allocation Table

Band PL definition Powerlevel (PL)
GSM900 Lowest 19
GSM900 Mid 12
GSM900 Highest 5

GSM1800/1900 Lowest 15
GSM1800/1900 Mid 8
GSM1800/1900 Highest 0

1.5 Test Limits

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

1. Since the coupler introduces higher measurement inaccuracy, some measurements
may have wider limits than stated in the GSM specifications.

2. The direct line connection limits conform to the phase 2 GSM specification.

2 Test Sequence using an RF Shield Box and Coupler

2.1 Initializing and Call Setup

Parameter Value Unit
BCCH Mid Ch
TCH Mid Ch
TX power level High PL
RF output power -40 dBm
System GSM 900

2.1.1 Sequence

1. Initialize instrument

2. Insert a test-SIM and attach a fully charged standard battery to the mobile. It’s
very important that a fully charged battery is used otherwise there is a high risk for
incorrect test results.

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

Rohde & Schwarz Shield Box and Coupler

4. Turn on the mobile and wait for registration.

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

6. Close the lid on the shielding box.
