Arbitrary waveform generator is the best instrument for simulation experiment. Arbitrary waveform generator is a kind of signal source, it has all the characteristics of the signal source.
The arbitrary waveform generator is different from the signal generator, which has the ability to generate other signal sources. So it is suitable for all kinds of simulation experiments.
In the selection of arbitrary waveform generator should be concerned about its ability to edit and waveform survival and download, but also pay attention to the number of output channels. In order to compare the phase shift characteristics of the two signals synchronously, and reach the simulation experiment condition.
