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:
