7700VMDA, 7700VMDA-2Q

Video Monitoring Reclocking Distribution Amplifier

  • VistaLINK® enabled

The 7700VMDA Reclocking Distribution Amplifier provides inexpensive distribution and composite encoder monitoring of your SMPTE ST 259 (270MB/s) serial digital video signal. The 7700VMDA features an auto-equalized input with seven outputs that can be selected as either SDI or composite analog. The 7700VMDA-2Q has two channels, each with three selectable outputs, or it can be used as a single input DA with six outputs.

The 7700VMDA and 7700VMDA-2Q occupy one card slot each and can be housed in the 1RU 7801FR frame which holds up to four single or two dual slot modules, the 3RU 7800FR frame which has a 15 slot capacity, the portable 3RU 350FR frame which has a 7 slot capacity, or a standalone enclosure which holds a single module.

Features
  • Features independent isolated output drivers to ensure no cross channel loading effects (i.e. no need to terminate unused outputs)
  • VistaLINK® capable for remote monitoring, control and configuration capabilities via SNMP. VistaLINK® is available when modules are used with the 3RU 7800FR frame and a 7800FC VistaLINK® Frame Controller module in slot 1 of the frame
