Mobile Communications Test System

These systems consist of various measuring instruments based around the MT8820A Radio Communication Analyzer and special test software. They can be used for executing the W-CDMA measurements specified in sections 5 (Transmitter Tests) and 6 (Receiver Tests) of the 3GPP TS34.121 specifications. The ME7877A additionally executes GSM measurements in the 3GPP TS51.010 specifications.

Fast measurements and simple operation make these systems ideal for R&D link tests and mobile terminal recognition tests, as well as for production line lot tests and QC inspection tests.

The ME7877A system configuration is:

• MT8820A Radio Communication Analyzer for TRX measurement with call processing
• MX787720A W-CDMA/GSM Measurement Software
• MS8609A Digital Mobile Radio Transmitter Tester for spurious measurements
• MN7476A RF Interface unit for signal filtering (internal configuration is changed according to the frequency band)
• MN7451A RF Switch Driver Unit for switching the MN7476A internal signal path
