The Invert, Integrate and Filter functions process informa-
tion from just one waveform (or source) and place the
result in another Waveform memory (or destination). Invert
is almost the same as the INPUT invert function found
under the
or
menu. Integration allows you to
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.
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.
