VDA-1002

Analog Video/Tri-level Sync Distribution Amplifier

The VDA-1002 is an analog video distribution amplifier with a differential looping input and eight outputs. Signal status is controlled from the card edge. Signal status is provided to indicate the input signal presence. The differential input provides rejection of hum and other artifacts on incoming signals. The new nine slot-wide VDA-1002-3NRP combined with nine VDA-1002 cards maximize analog video distribution to 70 BNC outputs with internal looping of input signal. Two VDA-1002-3NRP rears (with 18 VDA-1002) can be installed in a Densité 3 frame, giving a total of 140 BNC output per 3 RU for reference distribution.

FEATURES

  • Analog video differential input with passive loop-through
  • 8x 75Ω outputs
  • Supports NTSC and PAL video standards
  • 90 MHz analog video bandwidth
  • Control of gain from the card edge
  • Status LED and remote reporting
