Arbitrary Waveform Generator Vs Function Generator

Arbitrary function generators refer to function generators that can generate a periodic user defined waveform which typically consists of exactly 16 348 points using dds.

Arbitrary waveform generator vs function generator.

Unlike a function generator that produces a small set of specific waveforms an awg allows the user to specify a source waveform in a variety of different ways. These generators will often include capabilities to provide common function generator waveforms such as sine square and triangle waves. What is an arbitrary waveform generator used for. In general there are times when there is a need to generate a signal not provided as a standard option by signal generators in these situations an arbitrary generator can offer a technique to produce the desired signal.

An arbitrary function generator afg produces oscillating energy that takes the form of periodic or one shot waves. The word arbitrary denotes a user s ability to create waveforms beyond the permanent contents of the instrument s internal memory. Signal generators are subdivided into categories that include arbitrary function generators afgs and arbitrary waveform generators awgs. Choose the best signal generator and get the most from it.

An arbitrary waveform generator awg or arb is a sophisticated signal generator that generates arbitrary waveforms within published limits of frequency range accuracy and output level. What is the difference between an afg and an arbitrary waveform generator awg. A function generator that allows the user to create or upload custom waveforms to the generator and provide them at user defined frequencies. An arbitrary waveform generator awg 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.

To look at how an arbitrary function generator works it is necessary to look at the operation of a direct digital synthesizer. This paper discusses the key features and applications of keysight signal generators.
