A typical application of the Deskew I/O is to place two signals with a phase shift on top of each other in the scope screen.
An other typical application of the Deskew I/O is to remove a phase shift from a current signal, caused by a current probe, in order to perform correct power calculations.
To control the behavior of the Deskew I/O, several properties are available. These can be accessed via a popup menu which is shown when the I/O is right clicked. The properties can also be accessed through its settings window which is shown when the I/O is double clicked.
The setting Mode defines if the source's signal is shifted by a certain amount of time or by a certain amount of samples.
The setting Skew determines the amount a signal is shifted. A positive skew shifts the signal to the right (later). A negative skew shifts the signal to the left (earlier).
