Quick tips
Double clicking on a math e xpression opens the Math Equation Editor.
Math definitions are not implemented if the sources a re not valid.
Math waveforms are created from analog channel, reference, math source waveforms and from measurements.
Digital channels are not valid in math waveforms. However iCapture w aveforms are valid in math waveforms.
Use Digital Properties to set the digital threshold of analog channels.
Measurements are taken on math waveforms in the same way as on channel waveforms.
Math waveforms derive their horizontal scale and position from the sources in their math expressions. Adjusting these
control
s for the source waveforms also adjusts the math w aveform.
If Autos
cale is not checked, vertical scale and position are not calculated when a math w aveform is turned on or the
math equation is changed.
Magnify math waveforms using MultiView Zoom; use the mouse for positioning the zoomed area.
See the online help for more information on arbitrary math filters.
