Abstract
Abstract A waveform video monitor and vectorscope provides microprocessor control of a front panel display and, in one embodiment, includes six video inputs for complete composite and component testing. The monitor also includes electronic character generation capability. The microprocessor controls switching between two or more modes of operation and the display is blanked between switching.
