In some applications, such as the measurement of the total phase shift of a filter, it is useful to
continuously display the phase. To do so, activate the Unwrap phase function by clicking the Unwrap
phase checkbox in the Trace configuration box
display as shown below:

Hint: Optionally you can limit the unwrapping to a specific frequency range. Use the Begin
and End check boxes and corresponding entry fields to define a frequency range in that the
phase shall be unwrapped. This is especially useful when the phase result contains a lot of
noise in a specific frequency range.
