CMU200 Chinese Operation Guide CMU200 Operation Training Chapter 1 CMU200 Introduction 1 CMU200 Application and Basic Functions CMU200 is a comprehensive tester that simulates a base station during testing and tests the performance indicators of wireless terminal products through the Um interface. In addition, CMU200 can also be used as a signal source and spectrum analyzer in conjunction with other instruments. As a comprehensive tester, it supports almost all protocols: MS Test GSM400, 900, 1800, 1900, TDMA IS 136, AMPS, CDMA IS 95, WCDMA, CDMA2000, EDGE, etc. Of course, the support of different protocols requires us to load different versions of software. Therefore, it can be said that CMU200 is a modular design that is completely future-oriented. Since the basic unit of CMU200 includes the functions of signal source/power meter, oscilloscope and simple spectrum analyzer, CMU200 is widely used in the following fields: RF development module design module test in production final test in production functional test characteristic test advanced maintenance quality inspection basic instrument of test system base station simulation II. Main advantages of CMU200 The design of CMU200 not only meets the current test needs, but also provides a lot of spare resources for future upgrades. Its advantages are mainly reflected in the following aspects: Multi-standard support test platform fast test speed high test accuracy light weight low power consumption good compatibility III. Buttons and interfaces of CMU200 The front panel of CMU200 is mainly composed of VGA display screen, software on both sides of VGA, hot keys below, various hard keys on the right (FUNCTION, SYSTEM, DATA, VARIATION, CONTROL) and various interfaces. The figure below is the front view of CMU200. Figure 2-1 CMU200 front view The rear panel of CMU200 is shown in the figure below. It mainly consists of signal and synchronous input and output ports, remote control, peripheral device interfaces, power supply and its switch. Figure 2-2 CMU200 rear view The following is a brief introduction to various buttons and interfaces. FUNCTION Pre-select menu: MENU S……
