The Waveform Monitor

The Waveform Monitor is actually a whole family of scopes that shows different analyses
of luma and chroma using waveforms.

What Is a Waveform?

To create a waveform, Color analyzes lines of an image from left to right, with the resulting
values plotted vertically on the waveform graticule relative to the scale that’s used—for
example, –20 to 110 IRE (or –140 to 770 mV) on the Luma graph. In the following image,
a single line of the image is analyzed and plotted in this way.
