  • Button touch instead of coaxial cable replacing reduces pulse width setting time.
  • Pulse waveform stability has improved, allowing highly-reproducible testing.
  • Consumable parts reduction cut down running cost.
  • Common mode/normal modes are easily switched between by a short plug.
  • “Test time setting” new function simplifies test time setting.
  • Wiring became easier thanks to a built-in 50Ω terminator resistor design.
  • Repetition cycle became faster. Due to high repetition, malfunction occurrence rate is up and test time is shortened.(only INS-S220)
  • Outlet Panel allows direct connection of EUT AC plug.(option)
  • Various tests are available by using different probes and coupling clamps.(option)
  • Using of external CDN allows testing to 3-phase EUTs.(option)
  • Dedicated software simplifies testing with various test conditions (option, applicable to INS-S420 only)

  

• To solve the trouble in the market Test pulse with adjustable high frequencies and energy volume

  

  Narrow pulse of 50-100ns width although contains small energy, greatly affects electric circuits due to two transient fluctuations of short-time rise and fall and inductive coupling by steeply generated electromagnetic field.

  Narrow pulse of 50-100ns width although contains small energy, greatly affects electric circuits due to two transient fluctuations of short-time rise and fall and inductive coupling by steeply generated electromagnetic field.
  Wide pulse of 800ns-1000ns contains more energy, making it easy to apply large voltage fluctuations to the circuit.
  The rise time of impulse simulator is faster than IEC61000-4-4 fast transient/burst test and contains high frequency components up to 1GHz.
  Therefore, when noise is applied to the EUT, it is easier to penetrate and affect the electronic circuit.
  In addition, since the included frequency spectrum components and intensity differ depending on the pulse width of the impulse, it is recommended to conduct tests with several types of pulse widths.
  

• Improved reproducibility of test results Allows for more quantitative testing

  

  By changing from the conventional mercury relay to the semiconductor relay, the stability of the test pulse waveform has been improved, enabling tests with more quantitative and highly reproducible test results than before.
