An acquisition instrument - usually an oscilloscope or logic analyzer - is probably the first thing that comes to mind when you think about making electronic measurements. But these tools can only make a measurement when they are able to acquire a signal of some kind. And, there are many instances in which no such signal is available unless it is externally provided.
The arbitrary function generator (AFG) serves a wide range of stimulus needs and is actually the prevailing signal generator architecture in the industry today. The AFG offers unique strengths, and, moreover, it offers a way to modulate the signal from internal or external sources, generate frequency sweeps or output signal bursts. In this primer, we show 25 common applications for which an AFG can be used.
