Figure 3–98: H Bars Cursors Measure an Integral Math Waveform
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 horizon-
tal 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 waveform.
10. Read the time difference between the cursors from the : 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:
Read the integrated voltage over time between the Xs of both paired
cursors in volt-seconds from the : readout.
Read the integrated voltage over time between the X of the selected
cursor and the reference indicator of the math waveform from the @:
readout.
