Arbitrary Waveform Generator Block Diagram

A common awg block diagram a closer look at each arbitrary waveform generator awg functional block 1.

Arbitrary waveform generator block diagram.

The operation of the dds within the arbitrary function generator can be envisaged by looking at the way that phase progresses over the course of one cycle of the waveform. With scripting a signal generator can respond to these digital control signals on the fly without stopping generation of its waveform. These waveforms can be either repetitive or single shot once only in which case some kind of triggering source is required internal or external.

While lacking some of the features in a modern autonomous signal generator front panel controls permit the operator to select any of a dozen or so waveforms in addition to arbitrary waveform creation. Modern digital oscilloscopes generally contain a built in afg. These types of generators have limited bandwidth and costlier than function generators. The basic block diagram of the dds based arbitrary waveform generator is shown below.

Also frequency period amplitude and offset can be adjusted. An arbitrary waveform generator awg is a piece of electronic test equipment used to generate electrical waveforms. A common use of an arbitrary waveform generator is to stimulate a system with a complex waveform. It has a display screen that shows an exact picture of the arbitrary waveforms that helps in avoiding the chance of mistake while selecting waveform from memory.

The resulting waveforms can be injected into a device under test and analyzed as.
