Compact Video and Audio Signal Generator

The VSG-401 is a ½RU-wide, dual-link, 3G/HD/SD signal and sync generator. Part of the Imagine Communications 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 provides four SDI test signal outputs with selectable format, frame rate and signal type, and 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). Also included are two sync outputs selectable as blackburst or tri-level sync and a reference input for blackburst or tri-level sync.

The test signal outputs on the VSG-401 allow source ID selection up to 19 characters. Users can add continuous motion of a bouncing block to any test pattern except check field.

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

■ Small form factor
■ Four outputs (two for dual link), selectable as 3 Gb/s, HD, SD or DL
■ Two blackburst or tri-level sync outputs
■ Two AES/EBU outputs
■ Up to 16 channels of embedded audio test signals
■ Selectable audio level and frequency
■ 19-character source ID can be added to test signals
■ Genlock to standard color, black or tri-level sync
■ Genlock auto external or internal settings
■ Front-panel genlock and input status LED
■ Ethernet port for updates and web browser
