Compact Video and Audio Signal Generator

The Videotek® VSG-401 is a 1/2RU wide, single channel SDI test generator with single link and dual link operation modes. Either four outputs for single link SDI 3 Gb/s, single link SDI 1.5 Gb/s or single link SDI 270 Mb/s or two outputs of dual link SDI (2 x 1.5 Gb/s) can be selected by the user. Part of the Videotek Compact Monitor Series, the unit is small in size and light in weight, making it a perfect fit for all broadcast television and post production environments.

The VSG-401 can be externally referenced to color black (black burst) or tri level sync with user settings for the test generator for video format, frame rate and signal type, with up to 16 channels of embedded audio, with group enabled settings and global settings for amplitude and frequency. There are two AES outputs, with one output selectable as word clock or digital audio reference signal (DARS). The user can add continuous motion of a bouncing block to any test pattern except check field and the output of the test generator has a source ID function with user selection of nineteen characters.

The VSG-401 is simple to operate, with an Ethernet port facilitating software updates and a built-in Web UI for web browser control. A 110/220 universal AC adapter provides the required DC voltage power input.
