501ADA-EQ

Analog Video Distribution Amplifier with Cable Equalization

Product Manual Product Manual
VistaLINK® enabled

The 501ADA-EQ Analog Distribution Amplifier is a general purpose amplifier for distributing 75Ω analog video signals.

The 501ADA-EQ features one balanced equalized input with nine unbalanced outputs. The 501ADA-EQ amplifier has been designed to distribute a wide range of analog video signals. It can also distribute other pulses and signals that are less than 2V p-p.

The 501ADA-EQ is housed in the 3RU 500FR exponent frame that will hold up to 16 modules.

Features
  • 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
  • Jumper selectable fast or slow back porch clamp
  • DC level control when clamp is enabled
  • Cable equalizer adjustment range: 0 to 300m of Belden 8281 or 1694
  • 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
    • EQ Warning
