Used Anritsu MT8820A Radio Communication Analyzer

The MT8820A Radio Tester covers the frequency range from 30 MHz to 2.7 GHz and is designed to perform transmitter and receiver tests on 3G W-CDMA UE terminals in accordance with 3GPP TS34.121 and GSM terminals for both R&D and manufacturing applications.

With appropriate measurement software and hardware options installed, this single platform supports evaluation of all the main transmission/reception test items for W-CDMA terminals including HSDPA.

3GPP call processing is also supported, allowing both functional tests and transceiver measurements to be made in a call processing state. In addition, the voice signal from the terminal can be echoed-back during conversation in order to perform a simple voice communications test. Audio codecs are also available for real-time communication with terminals.

Advanced DSP and parallel measurement technologies dramatically reduce wireless manufacturing and inspection test times. Furthermore, multiple measurements can be selected for batch measurement. A one-touch operation allows selected batch measurements to be executed repeatedly a designated number of times. Pass/fail evaluation of the main measurement items -- including transmission frequency, modulation accuracy, output power, adjacent channel power, occupied frequency bandwidth and BER -- can be performed easily and quickly.
