Waveform Computation
Explanation
Addition, subtraction, multiplication, and division can be performed between channels.
Computation Target Channels
CH1 to CH16, Math1 to Math7
Computation range: Start Point/End Point
By default, the measurement range is
±
5 divisions of the display frame on the time axis.
You can limit this range.
The concept of the computation range is analogous to the concept of the selectable
range of cursor display position in cursor measurement.
For details, see “Selectable Range of Cursor Position” in section 11.4.
Scaling
Set the upper and lower limits of the math waveform display.
Auto:
The upper and lower limits are set according to the computed result.
Manual:
The upper and lower limits can be set arbitrarily. The selectable range is
–9.9999E+30 to 9.9999E+30.
Unit
Unit can be set arbitrarily using up to four characters. The specified characters are
applied to the scale values.
Linear Scaling
When performing computation on a channel that has linear scaling set, the computation
is performed on the scaled value.
Notes on Computation
Computation is not executed when you change Start Point or End Point while the
computation is stopped. Be sure to press Exec to perform the computation again. If you
do not, the waveform will not be displayed correctly when the screen is redrawn.
Note
While computation is in progress,
is displayed at the upper left of the screen.
