Every major radio communication system in the world, including GSM/DCS1800/PCS1900, IS-136A, PDC, and PHS, can be evaluated using just one MT8801A Radio Communication Analyzer, covering the 300 kHz to 3 GHz frequency band in one hardware platform, and the dedicated measurement software options. The call processing test and sensitivity test using the loopback method are possible for GSM/DCS1800/PCS1900 and IS-136A. MT8801A features include batch measurements of transmission test items, calibration functions, wide-band power meter, adjacent channel power measurement, constellation display functions, receiver sensitivity measurement, measurement of antenna power rise/fall edge characteristics, and a call processing function.
