URMA2000 Wideband Amplifier

Urma2000 is a new family of amplifiers with a high output level. They are designed to compensate insertion losses in thedistribution cable network with high channel loading. The amplifiers have built-in electronic slope and level adjustments, with the ability to control both locally and remotely. A high output level allows to reduce the amount of active equipment in the network, which increases its reliability.

URMA2000 Wideband Amplifier

  • Electronic level and slope adjustment
  • High output level of 114 dBμV
  • Inter-stage level and slope adjustments
  • Plug-in modules for the output splitter
  • Remote access for the monitoring and control system via Ethernet
  • Built-in remote control allows transmitting amplifier
    parameters to operator, and controlling the amplifier via
    Ethernet
