Arbitrary Waveform Generator Technologies
An Explanation of Technologies and Terms used for Arbirtrary Waveform Generatos - DDS and Variable Clock - AFG and AWG
- A Technical Information Tour for Customers
Recently DDS (direct digital synthesis) based function generators have
been developed into arbitrary/function generators with impressive
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 many more real-world problems.
Variable clock architecture for ARBs avoids the limitations of DDS
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
Before purchasing a generator intended for arbitrary waveform use, it is
important to discover which technology it uses.
