Interference Blanker Units

Interference Blanker Units are Line Replaceable Units or LRU’s.  Used primarily by Airborne and Shipborne Military Platforms. They co-ordinate the radar & RF transmitters and receivers’ communications.

However, their main purpose is to prevent interference from these technologies signals when operating on the same frequencies. This is achieved by creating blank suppression signals which disable sensitive receivers during strong transmissions.

How it operates

The EON Instrumentation Interference Blanker units (IBU) accept pulse inputs from numerous transmitters and generates and distributes blanking suppression pulse outputs to affected receivers.

Features of Interference Blanker Units

  • Accepts wide range of voltage levels and pulse frequency inputs that can be adjusted for the output triggering threshold
  • Pulse Width and Delay of suppression signal can be combined into one or more outputs.
  • Bidirectional Inputs/outputs accommodate ARINC Bus connections
  • Discrete inputs dynamically enable or disable individual blanking inputs from blanking map
  • All IBU’s provide individual signal threshold, pulse width and delay adjustments
  • Depending on the model, adjustments can be made using potentiometer controls on the unit or via a computer workstation which can create a blanking map that is downloaded to the unit’s memory.
  • Standard Connector Types / Impedance can be easily modified
