What is a Signal GeneratorThe signal generator or signal source is exactly what its nameimplies a generator of signals used as a stimulus for electronicmeasurementsMost circuits require some type of input signal whose amplitudevaries over time The signal may be a true bipolar AC1 signal withpeaks oscillating above and below a ground reference point or itmay vary over a range of DC offset voltages either positive ornegative It may be a sine wave or other analog function a digitalpulse a binary pattern or a purely arbitrary wave shapeThe signal generator can provide ideal waveforms or it may addknown repeatable amounts and types of distortion or errors tothe signal it delivers This characteristic is one of the signalgenerators greatest virtues since it is often impossible tocreate predictable distortion exactly when and where its neededusing only the circuit itselfThe response of the DUT in the presence of these distortedsignals reveals its ability to handle stresses that fall outsidethe normal performance envelopeSignal Generator TutorialsThe signal generator tutorial information found here will helpyou learn more about signal generator basics and their contributionto a complete test and measurement solutionFunction generatorLeader Instruments LSG15 signal generatorA function generator is a device which produces simplerepetitive waveforms Such devices contain an electronicoscillator a circuit that is capable of creating a repetitivewaveform Modern devices may use digital signal processing tosynthesize waveforms followed by a digital to analog converter orDAC to produce an analog output The most common waveform is asine wave but sawtooth step pulse square and triangularwaveform oscillators are commonly available as are arbitrarywaveform generators AWGs If the oscillator operates above theaudio frequency range 20 kHz the generator will ofteninclude some sort of modulation function such as amplitudemodulation AM frequency modulation FM or phase modulationPM as well as a second oscillator that provides an audiofrequency modulation waveformArbitrary waveform generatorAn arbitrary waveform generator AWG or ARB is a sophisticatedsignal generator that generates arbitrary waveforms See Answer
