Key Characteristics of Signal Generators and Modulation Methods

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 amplifiers, or even to entire modules, in order to ascertain and test the component’s behavior and characteristics. Beyond the output of spectrally pure signals, a key function of signal generators is the generation of analog and digitally modulated signals. The guide also provides important signal generator specifications and parameters that should be considered when choosing a signal generator.
