The 1RU Half-Rack VSG-401 Compact Video and Audio Signal Generator from Image Communications is a single channel SDI test generator with single-link and dual-link operation modes. You can select either four outputs for a single-link SDI 3 Gb/s, a single-link SDI 1.5 Gb/s, a single-link SDI 270 Mb/s, or two outputs of dual-link SDI (2 x 1.5 Gb/s). The unit can be externally referenced to color black (black burst) or to tri-level sync with user settings. This video and audio generator is used to test video format, frame rate, and signal type. It provides testing for 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). You 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.

External reference input (looping): Color black (black burst) or tri-level sync
Single-channel test generator with four outputs (two outputs for dual-link): Single-link SDI supports 3 Gb/s or 1.5 Gb/s, and 270 Mb/s Dual-link SDI supports 2 x 1.5 Gb/s
19 character source ID can be added to test signal output
Single channel of selectable color black (black burst) or tri-level sync reference output (2 outputs)
Two AES/EBU outputs (one selectable as word clock or DARS)
Up to 16 channels of embedded audio test signals
Selectable audio level and frequency
Front panel control with external reference input status LED
Ethernet port for updates and built-in Web UI
