The Invert, Integrate and Filter functions process informa-

totalize the waveform over a period of time, showing the
real power dissipation when the waveform changes levels.
To use the Integrate function:
1. Press .
2. Press to open the MATH MENU window.
3. Use to highlight MATH OPERATION, and
press to open the list box.
4. Use to highlight "integrate", and press
to select.
INPUT A has a good waveform to demonstrate integration
and Destination 1 is already displayed. If the resulting
waveform amplitude needs adjustment:
5. Use to highlight SCALE RESULT, and
press to open the list box.
6. Use for the appropriate scaling factor /25,
and press to select.
7. Press to close the window.
menu. Integration allows you to
With INPUT A set for DC coupling and the waveform
varying from about 0 to +4V, the result of the Integrate
function is a positive increasing line. When pulses occur on
INPUT A, the integral result increases accordingly as
shown in Figure 8-23. You can also use CURSOR
READING to make measurements on the Math results.
