One common piece of test equipment in any RF laboratory is the signal generator. The purpose of these devices is in the name itself “signal generator,” in that it generates signals with tunable properties such as amplitude, frequency, and wave shape. Signal generators are also called function generators, although, function generators often have more advanced features.
Signal generators are most commonly used to test the response of circuits using known and controllable input signal. In order to validate the output signal coming from the function generator it is common to validate that signal with an oscilloscope (but that’s the topic of a future post).
