After calling this menu entry the next two phase clicks (left mouse button) are used for setting this time window, unless the entry [ShmDocMenuAbortSelection Abort Selection] is activated.

    55Select the time window by clicking on its left and right border with the left mouse button, like selecting phases. The algorithm finds minimum and maximum within the window which are not at the windows border. The part of the waveform found between minimum and maximum is marked in pink color. Half of the amplitude difference between these points is taken as plain amplitude, the double of the time difference is read as signal period.
