Quick Tips
Math definitions are not implemented if the sources are not valid.
Math waveforms can be created from channel, reference, math source waveforms and from measurements.
Measurements can be taken on math w aveforms in the same way as on channel waveforms.
Math waveforms derive their horizontal scale and position from the sources in their m ath expressions. Adjusting these
controls for the source waveforms also adjusts the math waveform.
You can magnify math waveforms using MultiView Zoom; use the mouse for positioning the z oomed area.
See the online help for more information on arbitrary math filters.
Using Spectral Analysis
Use the
following procedure for predefined spectral math expressions. See the online help for more information.
