|electrical engineering an apparatus used to generate a signal consisting of a known oscillating voltage, usually between 1 microvolt and 1 volt, over a range of frequencies, to test electronic equipment|
electronic test instrument that delivers an accurately calibrated signal at frequencies from the audio to the microwave ranges. It is valuable in the development and testing of electronic hardware. The signal generator provides a signal that can be adjusted according to frequency, output voltage, impedence, waveform, and modulation
