The highlighted section of the following figure illustrates this use of the module.
Tip: Turning on WaveStream or persistence during deskew adjustment provides an ideal display
for visual inspection of the deskew adjustment accuracy.
• In User Edge trigger mode, it’s easier to measure deskew accuracy with the Skew parameter
(shown as follows) over multiple acquisitions. From the menu bar, select Measure → Measure
Setup. On the P1 dialog, select your inputs C2 and C6 (C2 from the Slave), respectively, and the
Skew measurement parameter from the pop‐up window.
At this point, go to the main Measure dialog and mark both the Show Table and Statistics
checkboxes. You can then easily view min, max, and sdev measurements to ensure your deskew
adjustments are within an acceptable range.
The Skew parameter should return an sdev value of ~2.5ps and the min and max values should be
equally distributed around zero. For most accurate results, use as fast an edge as possible.
