Arbitrary Generators and Arbitrary Waveform Generation

  Arbitrary Waveform Generator Products from Aim-TTi - Thurlby Thandar Instruments

Aim-TTi and Arbitrary Generators

Aim-TTi has been an innovator in arbitrary waveform generators since the early days of the technology.

The TGA series are true arbitrary waveform generators (AWGs) using variable clock architecture to generate arbitrary waveforms. They also include full function generator facilities using DDS technology.

The TGA series is available with one, two or four channels.

This combination of arbitrary, function, and pulse generator capabilities is described by the term Universal Waveform Generator.

The full range of Aim-TTi generators can be viewed on the Aim-TTi website
or USA Web Site.

 Arbitrary waveform generator and arbitrary function generator - Understanding the Technology

Variable clock or DDS (direct digital synthesis)

Before purchasing a generator intended for arbitrary waveform use, it is important to discover which technology it uses.

Arbitrary generators can use either of two technologies - variable clock or DDS.

True arbitrary waveform generators use a variable clock architecture. Recently, however, DDS based generators have been developed into arbitrary/function generators with impressive specifications.

However, the DDS approach to arbitrary waveform generation imposes serious limitations which are not immediately obvious.

The alternative approach of a variable clock architecture offers a greater level of flexibility and can be used to solve more real-world problems.

Some manufacturers, who offer both types of generator, refer to DDS arbitrary generators as AFGs (arbitrary function generators) and to variable clock generators as AWGs (arbitrary waveform generators). Other manufacturers give no indication of the technology used for arbitrary waveform generation.
