8Signal Monitoring

Figure 8.1 Vectorscope and Waveform Monitors

In the previous chapter you learned that a video monitor is used to judge the quality of an image. To measure the video signal itself, you use electronic measuring tools. Traditionally in analog video this was done with oscilloscopes designed specifically for video signal measurement (Figure 8.1). Today signal measurement takes many forms. Professional video production centers will often have stand-alone instruments, similar to the oscilloscopes they replace. Often many of the functions of those instruments can be found built into video production software tools such as editing ...
