Also frequency period amplitude and offset can be adjusted.
Arbitrary waveform generator block diagram.
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.
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.
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 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.
A common use of an arbitrary waveform generator is to stimulate a system with a complex waveform.
The memory is clocked at the highest sampling rate supported by.
Modern digital oscilloscopes generally contain a built in afg.
Dds frequency synthesizer as used in an arbitrary function generator afg.
A common awg block diagram a closer look at each arbitrary waveform generator awg functional block 1.
With scripting a signal generator can respond to these digital control signals on the fly without stopping generation of its waveform.
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.
These waveforms can be either repetitive or single shot once only in which case some kind of triggering source is required internal or external.
