What is a Signal Generator?

The signal generator, or signal source, is exactly what its name implies: a generator of signals used as a stimulus for electronic measurements.

Most circuits require some type of input signal whose amplitude varies over time. The signal may be a true bipolar AC1 signal (with peaks oscillating above and below a ground reference point) or it may vary over a range of DC offset voltages, either positive or negative. It may be a sine wave or other analog function, a digital pulse, a binary pattern or a purely arbitrary wave shape.

The signal generator can provide “ideal” waveforms or it may add known, repeatable amounts and types of distortion (or errors) to the signal it delivers. This characteristic is one of the signal generator's greatest virtues, since it is often impossible to create predictable distortion exactly when and where it’s needed using only the circuit itself.

The response of the DUT in the presence of these distorted signals reveals its ability to handle stresses that fall outside the normal performance envelope.
