Digital Mobile Radio Transmitter Tester

The MS8604A offers full test performance in a single unit capable of evaluating the major characteristics of transmitters used in digital mobile communication worldwide. Applicable systems are PDC, PHS, NADC, digital MCA, GSM, DCS1800 (PCN), CT2, DECT, WCPE, PACS, RCR STD-39 and TETRA. In addition, the MS8604A has GMSK and p/4 DQPSK universal analysis functions for analysis of the GMSK and p/4 DQPSK modulation signal. It covers frequencies from 100 Hz to 8.5 GHz and measures spurious emissions over a broad frequency range. It can also measure RF signals directly up to 10 W (average burst power), and baseband devices can be evaluated using its I/Q signal input function (option).

The MS8604A is ideal for high-speed measurement of carrier frequency, modulation accuracy, antenna power, leakage power during carrier-off, transmission ramp-up and ramp-down power, and occupied bandwidth (adjacent channel power, spurious emissions, and signal transmission rate) of digital mobile transmitters. In addition to measurements conforming to EIA/TIA, ETSI, RCR, and MKK standards, DSP (digital signal processing) and high-speed 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.
