Analog Video Distribution Amplifier

Interact with this product in a Layout Tool:

The 500ADA Analog Distribution Amplifier is a general purpose amplifier for distributing 75Ω analog signals. The 500ADA features one balanced input with nine outputs. The 500ADA has been designed to distribute a wide range of analog video signals. It can also distribute other pulses and signals that do not exceed 2V p-p.

The 500ADA is housed in the 3RU 500FR Exponent frame that will hold up to 16 modules.


  • 75Ω or high impedance input (jumper selectable)
  • High common mode range and common mode rejection ratio (CMRR)
  • Gain Control
  • Jumper selectable AC or DC coupling
  • Looping feature with extenal "T" connector
  • Consistent input impedance if card power is lost
  • VistaLINK® capable for remote monitoring via SNMP (using VistaLINK® PRO) when installed in 500FR frame with 500FC VistaLINK® Frame Controller
  • Card Edge LED's

  • Module Status/Local Fault
  • Power Supply Status
