DESCRIBE THE USE AND PURPOSE OF A WAVEFORM MONITOR
The waveform monitor is a specialized oscilloscope which provides detailed or
varied video information.
television frame to a single segment of a desired line or even a single pulse shape
Consequently, the waveform monitor is much more adaptable to television
testing than the average scope. Its uses are much more suitable for system tests
than for individual circuit or circuit component troubleshooting.
The major difference between the waveform monitor and the oscilloscope is the
measuring scale. Examples of three of the scales for waveform monitors are shown
in Figure 3-1.
