variable pulse width (VPW)
Variable Pulse Width (VPW) means variable pulse width. The VPW function is a function in which the pulse width is changed at a constant pulse frequency. With this function, the duty cycle - that is, the ratio of the pulse top to the pulse bottom - can change between 0% and 100%.
The variable pulse width is a function that is used, among other things, in function generators for testing electronic circuits and assemblies, but also in radar technology.
