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.
