Impulse Noise Simulator


The INS-AX2 series simulators are the advanced version of the conventional manually operated INS-4020/4040 simulators, maintaining the identical interference signal characteristics while offering a new level of ease of use.


  • An innovative,motor driven coaxial switch mechanism eliminates the need to manually plug and unplug coaxial connectors, allowing a preset test sequence to be carried out seamlessly including pulse width and coupling mode changes, automatic voltage ramp and others.
  • As well as manual control, the simulator can be remote-controlled through a fiber optic computer interface. Windows control software is free-downloadable from NoiseKen website.
  • Floating output
  • 8 pulse widths installed: 10ns, 50ns, 100ns, 200ns, 400ns, 500ns, 800ns and 1000ns
  • Internal switchable terminators
  • Easily changeable and safety-interlocked outlet panel (EUT interface)
  • 3 channels EUT fail input
