Advances in software, microprocessors and display technology have expanded the capabilities of modern function generators. The latest models can produce a variety of signals, including common waveforms, arbitrary waveforms and sophisticated modulated waveforms. Many use direct digital synthesis (DDS), which creates a stable, accurate output for clean, low-distortion sine waves. DDS also enables square waves with fast rise and fall times.

The added capability gives you more flexibility for testing your devices. The hints in this application note will help you take advantage of the features of your function/arbitrary waveform generator so you can get your job done more easily.
