CMU200的主要长处
　　CMU200无线通信测试仪通过各种特性，最重要的是极高的测量速度和测量准确度，提供优良的成本效果。此外，该单元模块化结构的第二远端寻址有助于全部测量任务的智能和独立处理和快速控制程序的设计。
最高的准确度
　　在生产环境中，该单元的高准确度允许将DUT（被测设备）微调为最大电池耐用时间而不必损伤质量。在实验室中，开发工程师可以用CMU200部分地替代传统的高质量专用仪器，同时节省桌面空间。达到CMU200极高准确度的关键因素是，整个频率和动态范围的高精密测量校准，以及实时地补偿温度的影响。
全球标准的Rohde&Schwarz公司校准系统可以在靠近您的服务中心或数量允许时在您的场地检测CMU200的准确度。在我们的各服务中心正在实施这些标准化的自动校准系统的全球网络。每当您需要时便能进行高准确度和重复度的校准。您本地的Rohde&Schwarz公司办事处为该单元提供用户定制的服务合同。此外，对于大规模的用户可以提供紧凑的检验系统。
最快的速度
　　高处理速度是由于广泛使用了ProbeDSP＆#8482;技术、并行测量和创新的远端命令处理。
· ProbeDSP＆#8482;技术
模块化结构有赖于由强大中心处理器协调的分散的ProbeDSP＆#8482;处理。示波探头、专用于特定本地数据采集和工作负荷计算的DSP帮助保持分系统的最优性能，即使CMU200主机安装了附加模块也是如此。
· 并行测量
　　可以并行进行几个RX和TX的测量，这是通过CMU200模块硬件的快速响应、单元的高度整体处理能力以及避免专用操作的瓶颈实现的。采用ProbeDSP＆#8482;技术并行运行的例子有各种BER测量和同时进行的相位/频率误差、EVM、幅度误差和音频测量，或各种频谱测量。
· 创新的远端处理
　　新颖的第二寻址模式能够以几乎相同的方式寻址各CMU200分系统（不同的移动台标准）的类似的功能。利用这种类型的寻址，可以通过简单的剪贴操作编程各种新的远端测试程序，接着通过编辑各种特定命令，使该控制程序适应新的应用。第二寻址是完全SCPI一致的，这意味着，分系统地址，例如“WCDMA-FDD”，可以用一个表示不同分系统、另一移动通信标准的字符串来代替。
最高的可靠性
　　CMU200在机箱和各个部件之间以及在散热片和空气流之间采用了特别有效的散热管理，与不同模块的独立制冷循环一起，共同形成优化的制冷系统。
基本单元
　　不安装任何选件的基本单元可以用来测试第一、二、三代移动电话机的一般参数。CMU200基本单元是模块级测试任务，即所有蜂窝移动通信标准早期生产阶段的理想解决方案。
CMU200基本单元的组成部分有RF发生器和RF分析仪，它们由一个不依赖于网络的多功能时域菜单和一个综合的频谱分析仪作为补充。作为实例，上图显示了功率-时间特性的测量。
当CMU200在人工模式，通过结合图形和数值查看菜单便能选择最优的视图。CMU200的菜单结构十分平滑，并使用上下文敏感的选项、输入项和下拉菜单配置。

Product Index: GSM \ GPRS \ CDMA
Product Information: 60 years, Rohde & Schwarz company's mobile wireless technology is always standing on the forefront of the CMU200 Universal Wireless Communications Test Set, RF test and measurement we have inherited this tradition. CMU200 is the third-generation platform design, which provides a true scalable multimode functionality. CMU200 reflects the fact that long-term technical experience with Rohde & Schwarz company in the mobile radio field has been greatly enhanced. In recent years, the company has helped to create a highly successful mobile wireless systems, Rohde & Schwarz has become a leading manufacturer of mobile devices, many of the preferred supplier of mobile wireless test equipment market leader.
CMU200 is a mobile wireless test equipment as part of the overall scope, its all-encompassing, from the conformance test systems, to the system simulator, the contractor functional board test / final test systems and simple sales count pass / fail testing equipment. The basic unit with the module does not rely on the standard test functions, provide many general-purpose measuring equipment suitable for its broad and continuous frequency range, various types of standards development. If the adoption of all relevant options to be expanded, CMU200 can provide treatment 3G, 2.5G and including the first generation of analog test applications, including necessary hardware and software testing third-generation mobile communications equipment.
Low cost of ownership
Select CMU200 is focused on the future decision-making, due to the following factors, the total cost of the owner is certainly the lowest:
? Hardware and software components of a complete modular design, from the outset to avoid unnecessary investment, because there are certain characteristics of a future when the need for the possibility of, you only need to pay for features you need the cost of .
? If you need a certain time after an increase in the need to expand, CMU200 modular concept will adapt to this request, the unit can be on-site installation of a number of expansion options, you only need to pay for that you need that part of the cost.
* The concept allows a CMU200 unit installed two complete channels (RF, signaling and terms).
* Largest manufacturing output, four small machine disk unit high chassis, the smallest power consumption to allow the production of a compact spatial layout.
· CMU200 user-friendly, and even less experienced users will intuitively grasp without the need for intensive training.
? The new remote interface syntax reflects this truly multi-mode modular characteristics of the inherent tester.

The main strengths of CMU200
CMU200 Wireless Communications Test Set through a variety of features, the most important is the high measurement speed and measurement accuracy, providing an excellent cost-effectiveness. In addition, the modular structure of the second remote unit will help all the measurement tasks addressing the intelligence and independence in handling and rapid control program design.
The highest accuracy
In a production environment, the unit's high accuracy allows the DUT (device under test) was the largest fine-tuning of time without having to damage the battery and durable quality. In the laboratory, development engineers can use CMU200 part of the high-quality alternative to traditional dedicated equipment, while saving desk space. To achieve very high accuracy CMU200 key factor is that the entire frequency and dynamic range of high-precision measurement of calibration, and real-time to compensate for temperature effects.
Global standards Rohde & Schwarz's calibration systems can be in close proximity to your service center or the number of venues to allow you to detect when CMU200 accuracy. In our various service centers are the implementation of these standardized automatic calibration system, global network. Whenever you need will be able to repeat the high degree of accuracy and calibration. Your local Rohde & Schwarz's office for the unit to provide customized service contracts. In addition, users can provide a compact large-scale test of the system.
Fastest
High processing speed is due to the widespread use of ProbeDSP ™ technology, parallel measurements and innovative remote order processing.
· ProbeDSP ™ Technology
Modular structure relies on a powerful central processor from the coordination of decentralized ProbeDSP ™ treatment. Oscilloscope probe, dedicated to a specific local data acquisition and DSP computing workloads to help maintain optimal performance subsystems, even if the CMU200 host add-on modules installed as well.
* Parallel Measurement
Can parallel measurement of several RX and TX, which is the hardware modules by CMU200 quick response unit of the height of the overall handling capacity and avoid bottlenecks in implementation-specific operations. ProbeDSP ™ technology run in parallel with examples of various BER measurements and at the same time the phase / frequency error, EVM, magnitude error and audio measurements, or various spectrum measurements.
* Innovative remote processing
The second novel addressing mode is almost the same way be able to address the various CMU200 subsystems (different standards of mobile station) and similar functions. Take advantage of this type of addressing, you can simply cut and paste operation of the remote programming of new testing procedures, followed by editing a variety of specific commands, so that the control procedures to adapt to new applications. Second addressing is completely consistent with SCPI, which means that sub-system address, for example, "WCDMA-FDD", can be expressed with a different sub-systems, the other mobile communication standard strings instead.
The highest reliability
CMU200 in the chassis and the various components as well as between the heat sink and air flow between the use of a particularly effective thermal management, and independent refrigeration cycle, different modules, together form a refrigeration system optimized.
Basic unit
Any option not to install the basic unit can be used to test the first, second and third-generation mobile telephones in general parameter. CMU200 basic unit is a module-level testing tasks, that is, all cellular mobile communication standards early stages of product the ideal solution.
CMU200 an integral part of the basic units are RF generator and RF analyzer, which does not depend on the network by a multi-purpose time-domain menu and an integrated spectrum analyzer as a supplement. As an example, the diagram shows the power - temporal characteristics measurements.
When the CMU200 artificial model, through a combination of graphical and numerical view the menu will be able to choose the best view. CMU200 the menu structure is very smooth, and use context-sensitive options, entry and pull-down menus to configure.
The operation has been advanced ergonomics with the most compact, lightweight 4 units high chassis plate machine combination.
