Modulation And Signal Generation With R&S® Signal Generators

Signal generators play a vital role in electrical test and measurement. They generate the test signals that are applied to components such as filters and amplifier, or even to entire modules, in order to ascertain and test their behavior and characteristics. The first part of this educational note presents the applications for and the most important types of signal generators. This is followed by a description of the construction and functioning of analog and vector signal generators. To permit a better understanding of the specifications found on data sheets, a closer look at the most important parameters for a signal generator is provided.
