7. Press Function (main) V Bars (side). Use the general purpose knob
to align one of the two vertical cursors to a point of interest along the
horizontal axis of the waveform.
8. Press SELECT to select the alternate cursor.
9. Align the alternate cursor to another point of interest on the math waveĆ
form.
10. Read the time difference between the cursors from the D: readout. Read
the time difference between the selected cursor and the trigger point for
the source waveform from the @: readout.
11. Press Function (main) Paired (side).
12. Use the technique just outlined to place the long vertical bar of each
paired cursor to the points along the horizontal axis you are interested
in.
13. Read the following values from the cursor readouts:
H Read the integrated voltage over time between the Xs of both paired
cursors in voltĆseconds from the D: readout.
