High performance EMC noise scanner

Morita-Tech Desktop Noise Scanner WM7000 Series

WM7400 (up to A4 size)

The WM7400 is a high-performance EMC noise scanner capable of measuring up to A4 size, with the ability to detect noise over the 6 GHz band, measure omnidirectional magnetic flux, and identify the source of generation.

It covers a frequency range of 150 kHz to 3 GHz, or 150 kHz to 8 GHz.

* Patent pending
* Customizable measurement areas are available, tailored to your specific needs, with options for both smaller and larger sizes.
* Designs are subject to change without prior notice.

WM7300 (up to A3 size)

A 6GHz wild band high-performance EMC noise scanner that can identify the place where omnidirectional noise is emitted in a scanning area up to A4 size. The long cables and big size print boards that can’t be measured by WM7400 can be measured by the WM7300.

Frequency band：150KHz～3GHz/150KHz~8GHz

* The scanner can be custom made from design to manufacture, no matter the size of the target objects is smaller than scanning area or with a big size.
* The shape might be changed for refine without notice, please note.
* CISPR22 Patent Pending

Three reasons the WM7400
is chosen by engineers

Realizing the "Real EMC" (EMI+EMS)

By equipping the magnetic feld/electric field probe “MT-676 electromagnetic wave irradiation probe (option)” equipped with a newly developed spot (local) immunity function developed in-house, in acidition to the electromagnetic wave detection of near magnetic field and electric field, the “spot immunity test” by electromagnetic wave irradiation also can be realized.

In addition to inspecting products, it becomes easy to identify the places where electromagnetic wave sensitivity is high at the design stage of electronic devices and elucidate the mechanism electromagnetic noise occurs.

  • EMC : Electro-Magnetic Compatibility
  • EMI: Electro-Magnetic Interference
  • EMS: Electro-Magnetic Susceptibility

With our special viewer software, you can see the source of noise and EMS at a glance.

For EMI from the conventional model, high-speed and accurate noise measurement realized with dedicated (EMI ) Is software. The noise source can be seen at a glance by superimposing the noise map on the photograph of the measured object. Even in the immunity fest, the unicue location where EMS occurs can be visualized with this software (optional).

All the robots, softwares and probes are developed in-house!

We have achieved high performance and compactness by combining a highly reliable robot selected through years of research and development. a high-definition video camera, and a high-precision laser rangefinder. A wide variety of magnetic and object electric feld probes developed in-house enable wide band, high-resolution measurement according to the application
