ABSTRACT
The vectorscope, like the waveform monitor, is made up of a CRT, graticule, and knobs and buttons. The lines and markings on the graticule are used as the framework under which the chrominance of the signal is displayed for reference. The controls adjust the placement of the chrominance display pattern. Other vectorscopes may have controls in a different configuration, but the functions detailed in this chapter will be available on all models. To clearly introduce the concepts of a vectorscope, the Tektronix 1720, with dedicated controls, will be used as a reference.
