The Waveform Monitor is an operational monitor providing the signal monitoring features useful to the graphics workstation, telecine, all of the video features, Transmitter, or camera setup operator, for use by a person responsible for the look and continuity of the television picture. It instills confidence that creative adjustments can be made without violating transmission standards, thus assuring trouble-free distribution throughout a facility.
The wavefrom Monitor to provide a more comprehensive evaluation of the digital transport layer and is used in digital production and master control operating centers, and provides data analysis capabilities for the installation and maintenance engineer.

If you described in excruciating detail the nature of the video signal. It's now time to use a piece of equipment that will allow us to see these precise wave formations. We need a "wave-form monitor"
For so long now, we've been describing CRTs as having screens that are scanned from left to right, and top to bottom. Nobody says we have to do it this way. In fact, with the exception of television picture tubes, CRTs are rarely scanned this way.
A waveform monitor is a sort of "programmable CRT." Its left-to-right scanning pattern is very similar to that of a picture monitor, but we can change the rate of that scanning. The vertical scanning pattern is not our usual top-to-bottom sawtooth, but is a representation of the voltage present at the input terminal – normally 1 volt of video (from the bottom of sync to 100 units of white level). The brighter the video level is, the higher it appears on the face of the waveform monitor screen. We can adjust how sensitive the waveform monitor's amplifiers will be in the vertical dimension (the "gain" of the displayed image).
As well, the frequency response characteristics of the amplifier can be changed so we can see just the luminance, just the chrominance, or both components of the composite video signal. Finally, we can synchronize the waveform monitor's sweep to the video we're looking at, or to an external reference.
