NOISEKEN Impulse Noise Simulator INS-S220

Solve Market Noise Troubles -Beyond the Standards-

An ideal tester evaluates noise resistance of electronic devices due to discharge between contacts of switching devices, or arc discharge generated from electronic motors by generates simulated high-frequency noise with a rapid rise time.
With it’s high frequency component included in the testing pulse, and variable energy amount by changing the pulse width, it is capable of highly replicable noise testing against market’s noise troubles.

Impulse Noise Simulator






  • Faster pulse repetition cycle testing is now possible
    The high speed pulse-repetition-cycle improves malfunction occurrence, thus shortens testing time.
  • Simplifies pulse width setting
    Only button operation enables pulse width setting in 50ns steps, reduces setup time and connection errors.
  • Simplifies pulse width setting
    Only button operation enables pulse width setting in 50ns steps, reduces setup time and connection errors.
  • Improves test pulse waveform stabilities, enables highly replicable noise testing.
  • Saves cost by reduced number of consumable components.
  • Simplifies common/normal mode switch setting with short-plug design.
  • Enables easy wiring with built-in 50-ohm terminators.
  • Directly connects EUT AC plug with outlet panels. (Option)
  • Enables various testing with various probes and coupling adaptors. (Option)
  • Enables 3-phase 5 line testing with additional superimposing units. (Option)
