3.2 Go/No-Go Test

This test verifies that the radio parameters of the phone fulfil the EGSM900/GSM
1800/GSM1900 specification. If all measurements are approved, this will be confirmed. If
any faults are discovered, this will be presented either on the screen or printed out. It’s
possible to do this test either with antenna coupler from Rohde&Schwarz or RF adapter.
When using RF adapter a dummy battery shall be used.

It’s very important that a fully charged battery is used otherwise there is a risk for wrong test
results.

Antenna Coupler

according to the picture (Fig 1).

RF adapter

• Insert a test-SIM and a dummy battery. Assemble the RF adapter according to Fig 2 and

2.1. Connect the RF cable RPM 119 855 between the Test set and the antenna adapter.
