A logic analyzer that performs analog-type measurements on digital data includes circuitry in its acquisition system that is programmable to search through acquired data to detect analog-type signal characteristics. In a first embodiment, the logic analyzer includes a graphical user interface employing a drag-and-drop operation to apply one or more selected analog-type measurements to selected portions of the digital data record. In a second embodiment, a user may designate a particular waveform or data listing by means of a mouse-click. Each of the choices of analog-type measurements can be represented by an icon, or text, or both icon and text. Some of the analog-type measurements, among others, are pulse width, duty cycle, period, frequency, period jitter, and cycle-to-cycle jitter
