信号发生器在电气测试与测量中发挥重要作用, 可以生成用于滤波器和放大器等组件甚至整个模块的测试信号,以便测定和测试这些设备的行为和特性。本教学指南的第一部分首先介绍了信号发生器的应用和重要的信号发生器类型。随后,指南介绍了模拟和矢量信号发生器的构造与功能。为了更好地理解数据表中的规格数据,本指南详细介绍了信号发生器的重要参数。除了输出具有出色频谱纯度的信号之外,射频信号发生器的另一个重要功能是生成模拟和数字调制信号。因此,本教学指南的第二部分介绍了重要模拟和数字调制方法的相关原理。本教学指南的第三部分提供有关模拟和数字调制的练习内容。指南中描述的所有测量均使用 R&S®SMBV100A 矢量信号发生器和 R&S®FSV 频谱分析仪完成。

Welcome to our short video tutorials on how to test radars using Rohde & Schwarz test equipment. Access to most information about radar is pretty restricted, as many radar applications are military or secretive industrial research. To show you some basic Radar tests we have created RADAR demo tools, which functions at a frequency of 2.45 GHz, which is in the unlicensed 2.4 GHz Industrial, Scientific and Medical band. So we can even perform our tests in unshielded rooms. The frequencies are also used by radar operating in the ITU "S"-band from 2.3 to 2.5 GHz for air traffic control, weather and marine radar. The videos are suitable for 'from-the-scratch' introduction of R&S RADAR test equipment. They can also be used for plain introduction to the RADAR principle.
