an instrument that produces alternating-current (ac) voltages and currents
Signal generator that can produce sine, square, triangle and saw tooth output waveforms.
A voltage source capable of producing a variety of voltage waveforms of varying frequencies. Most common waveforms are square, sinusoidal and triangular.
Circuit that produces a variety of waveforms; can be constructed using a ROM, a DAC, and a counter.
A function generator is a piece of electronic test equipment used to generate electrical waveforms. These waveforms can be either repetitive, or single-shot (once only) in which case some kind of triggering source is required (internal or external). The resultant waveforms can be applied to a device under test and analyzed as they progress through the device, confirming the proper operation of the device or pinpointing a fault in it.
