Description

The Programmable Signal Generator (Three-Phase) generates a three-phase sinusoidal signal with programmable magnitude, phase, and frequency over time. You can specify one or two harmonics that can be overlapped on the signal fundamental frequency.

You can switch between continuous and discrete implementations of the block by using the Sample time parameter. To configure the block for continuous time, set Sample time to 0. To configure the block for discrete time, set Sample time to a positive, nonzero value.
