产品简介：
R&S®SFU广播电视测试系统用途广泛，技术领先。它把多台仪器的功能集成到4U高度的机箱内，并提供卓越的射频和基带性能。 正是因为其模块式的设计理念，R&S®SFU可以适用于用户不同的应用。它是用户用于改进已知数字电视标准产品质量以及研发数字电视新标准的理想工具。而要完成以上任务，以前需要多台仪器，现在只需R&S®SFU就可以完成，这种先进的设计使得操作也更为迅速、简单。
用户可以方便地切换运行参数（例如滚降、打孔率、QAM模式等等），并可轻松选择那些超过标准的运行参数值，供实验室研究使用。 对于像生成DVB-T/H信号等特殊应用，可设置关闭调制、单载波和载波群，并可扫描整个RF频段。
主要特性：
Product introduction:
The R&S®SFU radio and television test system has a wide range of uses and leading technology. It integrates the functions of multiple instruments into a 4U height chassis and provides excellent RF and baseband performance. It is precisely because of its modular design concept that R&S®SFU can be adapted to users' different applications. It is an ideal tool for users to improve the quality of known digital TV standards and to develop new digital TV standards. To complete the above tasks, multiple instruments were required before, but now only R&S®SFU can be completed. This advanced design makes the operation faster and simpler.
Users can easily switch operating parameters (such as roll-off, punch rate, QAM mode, etc.), and can easily select those operating parameter values that exceed the standard for laboratory research. For special applications such as generating DVB-T/H signals, modulation, single carrier and carrier group can be turned off, and the entire RF frequency band can be scanned.
