Arbitrary Waveform Generator Block Diagram

Modern digital oscilloscopes generally contain a built in afg.

Arbitrary waveform generator block diagram.

The memory is clocked at the highest sampling rate supported by. Also frequency period amplitude and offset can be adjusted. With scripting a signal generator can respond to these digital control signals on the fly without stopping generation of its waveform. A common awg block diagram a closer look at each arbitrary waveform generator awg functional block 1.

A digital representation of a waveform is loaded into awg memory through a variety of software applications such as matlab labview visual studio plus ivi and scpi. An arbitrary waveform generator awg is a piece of electronic test equipment used to generate electrical waveforms. Figure 27 shows a block diagram of a test scenario where a signal generator produces a series of different signals conditional on digital control signals coming from the uut. 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.

Dds frequency synthesizer as used in an arbitrary function generator afg. A common use of an arbitrary waveform generator is to stimulate a system with a complex waveform. The basic block diagram of the dds based arbitrary waveform generator is shown below. The resulting waveforms can be injected into a device under test and analyzed as.

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.
