Arbitrary waveform generator vs function generator.

This paper discusses the key features and applications of keysight signal generators. 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. The word arbitrary denotes a user s ability to create waveforms beyond the permanent contents of the instrument s internal memory. 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.

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. A function generator that allows the user to create or upload custom waveforms to the generator and provide them at user defined frequencies. This waveform can be defined by selecting user as the standard waveform and uploaded to memory using the define user standard waveform vi. Signal generators are subdivided into categories that include arbitrary function generators afgs and arbitrary waveform generators awgs.

What is an arbitrary waveform generator used for. These generators will often include capabilities to provide common function generator waveforms such as sine square and triangle waves. What is the difference between an afg and an arbitrary waveform generator awg. To look at how an arbitrary function generator works it is necessary to look at the operation of a direct digital synthesizer.

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. The arbitrary function generator uses integrated circuits intended for direct digital frequency synthesizers but enables an arbitrary waveform generator circuit to be created relatively easily and for an economic price.
