Math Waveforms
Once you have acquired waveforms or taken measurements on waveforms, the instrument can
mathematically combine them to create a waveform that supports your data-analysis task. For
example, you might have a waveform clouded by background noise. You can obtain a cleaner
waveform by subtracting the background noise from your original waveform. Or, you can
integrate a single waveform into an integral math waveform as shown below.
With spectral analysis you can analyze waveforms in the frequency domain. The interface is
similar to a dedicated spectrum analyzer, so you do not need to know the details of the underlying
algorithms. See the following figure.
