CMU200 is a comprehensive test instrument that can simulate base stations and test the performance indicators of wireless terminal products. It also functions as a signal source and spectrum analyzer. It supports multiple protocols and features a multi-standard testing platform, fast testing speed, high accuracy, lightweight design, low power consumption, and good compatibility.
The CMU200 is a modular communication test instrument that can simulate a base station, act as a signal source, power meter, oscilloscope and spectrum analyzer, and supports many protocols such as GSM, TDMA, CDMA, WCDMA, EDGE, etc. It is used in RF development, module design, production testing, quality inspection, and advanced maintenance.
The manual describes the front‑panel buttons and connectors, explains software version management and firmware upgrades via floppy or PCMCIA, and provides step‑by‑step procedures for GSM900 and GSM1800 testing, including power level, channel selection, and antenna‑coupling tests. This manual is written in Chinese.
