<p>A rise/fall time cursor display computes from digitized waveform data break points in the waveform, such as 20% and 80% amplitude points. These points are connected by a straight line that is stored with the waveform data in a display memory. Short horizontal lines may be added to the cursor at the 20% and 80% amplitude points to clearly show the break points and the slope of the edge of the waveform. Further from the horizontal difference in the amplitude points and the known sample rate the actual rise/fall time is computed for alphanumeric display with the waveform. <IMAGE></p> |
