Mobile Communication Test System

The ME7877A and ME7878A Mobile Communications Test Systems are automatic systems for testing the W-CDMA spurious emissions characteristics of W-CDMA mobile terminals. In addition, the ME7877A supports GSM spurious emissions measurements, and the ME7878A supports W-CDMA interference measurements.

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.

The ME7878A system configuration is:

• MT8820A Radio Communication Analyzer for TRX measurement with call processing
• MX787800A W-CDMA Measurement Software
• MS8609A Digital Mobile Radio Transmitter Tester for spurious measurements
• MG3681A Digital Modulation Signal Generator and MG3692B RF/Microwave Signal Generator for the interference signal source
• MN7476A RF Interface unit for signal filtering (internal configuration is changed according to the frequency band)
• MN7486A Interference Measurement 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
