Avoiding Phase Discontinuity in Arbitrary Waveform Generators

How To Avoid Phase Discontinuity in Arbitrary Waveform Generators

Phase discontinuity

The most common arbitrary waveform generation use case is to play back a waveform that is finite in length and repeat it continuously. Although often overlooked, a phase discontinuity between the end of a waveform and the beginning of the next repetition can lead to periodic spectral regrowth and distortion. This problem is also known as waveform discontinuity as described in this article.

Active Technologies True-Arb AWG software recently introduced a new unique feature called Parametric Waveforms to avoid this problem and to simplify the waveforms’ creation.
The Parametric waveforms simplify and speed up the creation of custom waveforms and now you can generate easily and in a flexible way, the signals for the most demanding applications, avoiding phase discontinuity.
The phase discontinuity produces a noticeable increase in distortion components in addition to the line spectra normally representative of a single sinewave.

The complete application note can be found here.
