Integral Math Waveform

Once you have displayed your integrated math waveform, use cursors to measure
its voltage over time.

1. Be sure MORE is selected (lighted) in the channel selection buttons and that

the integrated math waveform is selected in the More main menu.

2. Press CURSOR ➞ Mode (main) ➞ Independent (side) ➞ Func-

tion (main) ➞ H Bars (side).

3. Use the general purpose knob to align the selected cursor (solid) to the top

(or to any amplitude level you choose).

4. Press SELECT to select the other cursor.

5. Use the general purpose knob to align the selected cursor (to the bottom (or

to any amplitude level you choose).

6. Read the integrated voltage over time between the cursors in volt-seconds

from the 

: readout. Read the integrated voltage over time between the

selected cursor and the reference indicator of the math waveform from the
@: readout. (See Figure 3–104.)
