The TDS3VID transforms a TDS3000B oscilloscope into a full-featured video test tool. The module adds a vectorscope display (standard TV and HDTV-compatible) and graticules for color bars, as well as all the necessary triggering for existing and emerging line rate standards. The TDS3VID module also makes it possible to display an actual video image on the TDS3000B screen and select individual lines to examine in detail.
