产品指标： 300kHz-3GHz 产品信息： 频率：300 kHz to 3 GHz 　　 The MT8802A was designed to support the test needs of the manufacturing R&D and maintenance markets. All major radio communication systems in the world including IS-95 GSM/DCS1800/PCS1900 IS-136A AMPS/NAMPS P DC and PHS can be evaluated using just one MT8802A Radio Communication Analyzer covering the 300 kHz to 3 GHz frequency band in one hardware tform and the dedicated measurement software options. This tester supports Service Options 1 2 and 9 for IS-95 and J-Std-008 as well as call processing and sensitivity testing using the loopback method for GSM/DCS1800/PCS1900 and IS-136A. The call processing function transmission/reception measurement functions analog measurement function and the rmocouple power meter are provided as standard features. And when the spectrum analyzer function is added as an option the MT8802A becomes a general-purpose spectrum analyzer that covers the frequency range of 10MHz to 3GHz. 　　 FM radio transmi ssion/reception tests are simplified by using the analog measurement function and the optional spectrum analyzer function covering 10 MHz to 3 GHz is very useful for maintaining and measuring spurious near carrier on production lines. GPIB and RS-23 2C interfaces are standard so MT8802A can be incorporated easily into automated production lines or on-site automated testing systems. 　　 The time required for testing equipment on production lines is greatly reduced using the high-speed adjac ent channel power and occupied bandwidth measurement functions based on Anritsu’s proprietary measurement algorithm and DSP (Digital Signal Processing). 　　 Furthermore major transmission test items such as transmission frequency modulation accu racy (phase error) transmission power rise/fall characteristics of burst wave adjacent channel power etc. can be measured.
