频率范围：100KHz～8.5GHz 产品信息： The MS8604 offers full test performance in a single unit capable of evaluating the major characteristics of transmitters used in digital motile communication worldwide. Applicable systems are PDC,PHS,PADC,digital MCA,GSM,DCS1800 (PCN),CT2,DECT,WCPE,PACS,RCR STD-39 and TETRA. In addition,the MS8604A has GMSK and p/4 DQPSK universat analysis functions for analysis of the GMSK and p/4 DQPSK modulation signal. It covers frequencies from100Hz to 8.5GHz and measures spurious emissions over a broad frequency range. It can also measure RF signals directly up to 10W(average burst power), and baseband devices can be evaluated using its L/Q signal input function(option). The MS8604A is idesl for high-speed measurement of carrier frequency, modulatio accuracy,antenna power, leakage power during carrier-off, transmission ramp-up and rampdown power and occupied bandwidth (adjacent channel power, spurious emissions, and signal transmission rate)＊ ofdigital mobile transmitters.In addition to measurements conforming to EIA/TIA,ETSI,RCR,and MKK standards,DSP(digital signal processing) and highspeed measurement functions based on a unique measurement algorithm combine to greatly reduce the time required for manufacturing and inspecting transmitters. PTA functions enabling free programming of test procedures are provided as a standard feature. ＊:Measurement items depend on the measuremett software . For details, refer to the specifications.
