Additional Features: Frequency range: 30 MHz to 2.7 GHz Advanced DSP and parallel measurement technologies for fast test time 3GPP call processing including Registration; Origination, and Termination 12 Transmitter measurements items including Modulation analysis; Adjacent channel power ratio and Peak code domain error according to 3GPP TS34.121 Bit Error rate (BER) and Block Error rate (BLER) receiver measurements using 3GPP loopback method "One-touch" Batch measurement operating mode with Pass/Fail evaluation Multi-system W-CDMA / GSM capability 1xEV-DO support including external packet data communications measurement capability and IP data communications mode EDGE/EGPRS measurement software supporting MCS1-MCS4 (GMSK modulation) and MCS5-MCS9 (8PSK modulation) coding HSDPA call processing and RF transmission/reception measurements for mobile terminals with UE category 1 to 6, 11, and 12 Parallel phone measurement to increase measurement speed, reduce production costs, and save manufacturing space The MT8820A 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. Options also support EDGE/EGPRS and 1xEV-DO, as well measurements for two phones simultaneously. 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.
