Introduction
The phone allows computer controlled testing of vari-
ous test parameters.
This chapter includes the computer functions and rec-
ommended equipment setup to use when testing a phone
manually.
Call-Processing Tests
Most communications analyzers can simulate a cell site
in order to perform automatic call-processing tests.
Automatic call processing tests can be performed while
the phone is in standby mode.
Refer to the communications analyzer’s manual for de-
tails about performing call-processing tests. The follow-
ing call-processing test sequence is recommended:
1. GSM Mobile Originated Call
2. WCDMA Mobile Originated Call
3. GSM handover
4. DCS handover
5. PCS handover
Non-Signaling Test Measurements
In an event that the phone exhibits RF failures that pre-
vent call processing, the service technician may need to
perform some non-signaling tests. These tests will pro-
vide information regarding which stage of the phone is
failing prior to opening the phone for troubleshooting.
The following tests will be described in this chapter.
• GSM/DCS/PCS TX Power Output
• GSM RSSI
• WCDMA TX Power Output
The phasing parameters are stored in an EPROM in
the transceiver board. Each transceiver is shipped from
the factory with these parameters already calibrated.
However, if a board is repaired, these parameters should
be measured and, if necessary, adjusted (phased) with
the GP-Gate System. Checking and adjusting calibra-
tion parameters is also useful as a troubleshooting/diag-
nostic tool to isolate defective assemblies.
