The MT8815A is the fastest and most accurate mobile phone tester for repair applications, and the only tester that supports all popular 2G, 2.5G, and 3G technologies in one unit, including a scalable platform providing investment protection by allowing installation of new wireless formats. The MT8815A hardware platform covers a frequency range of 30 MHz to 2.7 GHz. When dedicated measurement software and hardware (options) are installed, this single platform supports evaluation of all the main transmission/reception test items for W-CDMA, GSM/GPRS/EGPRS, cdma2000 1xRTT (IS-2000), cdma2000 1xEV-DO, AMPS, and PHS terminals. Advanced DSP (Digital Signal Processing) and parallel-measurement technology greatly reduce the time required for the production and testing of mobile terminals. Combinations of parameters for batch measurements are freely selectable, and the number of repeat measurements for each measurement can be set independently. The selected items for measurement can be batch-processed through one-touch operation, enabling easy, high-speed Pass/Fail evaluation on major test items including transmission frequency, modulation accuracy, transmission power, adjacent channel power, occupied bandwidth and BER. The standard GPIB and RS232-C interfaces enable the MT8815A to be used in existing automated production lines or to be configured by automatic test systems in maintenance sites.
