Analog Waveform Monitors
A video monitor is used to judge the quality of an image. Electronic measuring tools known as oscilloscopes are used to measure the video signal itself. There are two types of oscilloscopes used to measure the signal, the waveform monitor and the vectorscope (Figure 8.1). This chapter covers the analog waveform monitor.
The waveform monitor is used to make sure the video signal is being recorded or reproduced within legal broadcast specifications. The following information about waveform measurements applies to all models of waveform monitors, even though the layout of buttons and switches may be different. There also may be some switches on certain waveform monitors that are not described here.
