Multiformat Sync Changeover Unit

The VSX-11-3G has 11 outputs that are switched from primary or secondary inputs as determined by input conditions or faults. The VSX-11-3G is designed for use in any video format environment and provides protection for primary reference signal loss. All channels have a user-selectable configuration. The VSX-11-3G accommodates SDI Serial Digital Interface SD/HD/3G, NTSC/PAL color black (black burst) and tri level sync and AES digital audio.

The VSX-11-3G can be used with the VSG-MTG Master Timing Generator, VSG-4TSG Test Signal Generator, VSG-4CSD Clock Systems Driver and VSG-401 Compact Video and Audio Test Generator. Packages including two of the aforementioned products and a VSX-11-3G are available for redundant, reference, test and reference, time/date and test systems.
