Arbitrary Waveform Generator Vs Function Generator

What is the difference between an afg and an arbitrary waveform generator awg.

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. 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. We should begin by asking. A function generator that allows the user to create or upload custom waveforms to the generator and provide them at user defined frequencies.

This paper discusses the key features and applications of keysight signal generators. This waveform can be defined by selecting user as the standard waveform and uploaded to memory using the define user standard waveform vi. The word arbitrary denotes a user s ability to create waveforms beyond the permanent contents of the instrument s internal memory. 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.

Choose the best signal generator and get the most from it. An arbitrary function generator afg produces oscillating energy that takes the form of periodic or one shot waves. To look at how an arbitrary function generator works it is necessary to look at the operation of a direct digital synthesizer. Signal generators are subdivided into categories that include arbitrary function generators afgs and arbitrary waveform generators awgs.

These generators will often include capabilities to provide common function generator waveforms such as sine square and triangle waves. 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.
