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
Morita-Tech Desktop Noise Scanner FAQ
1. What is the WM7000 Series used for?
The Morita-Tech WM7000 Series is used to scan and visualize electromagnetic noise sources on printed circuit boards, electronic components and electronic devices. It helps engineers identify where noise is generated, measure magnetic flux and support EMC troubleshooting during product development.
2. What can the WM7400 measure?
The WM7400 is designed for desktop EMC noise scanning up to A4 size. It can measure omnidirectional magnetic flux and help detect the source of electromagnetic noise on PCBs, components and electronic devices.
3. What is the difference between WM7400 and WM7300?
The WM7400 is suitable for measurement areas up to A4 size, while the WM7300 is designed for larger targets up to A3 size. The WM7300 is useful when longer cables, larger printed circuit boards or bigger electronic assemblies cannot be measured within the WM7400 scanning area.
4. What frequency range is supported?
Depending on the model and configuration, the WM7000 Series covers frequency ranges such as 150 kHz to 3 GHz or 150 kHz to 8 GHz. This enables wide-band noise source investigation for EMC design and troubleshooting.
5. Can it detect noise over 6 GHz?
Yes. The WM7000 Series is designed for high-performance noise scanning and can support wide-band measurement, including noise detection over the 6 GHz band depending on the model and configuration.
6. What is near-field noise scanning?
Near-field noise scanning is a method used to measure electromagnetic noise close to the surface of a PCB, cable or electronic device. By scanning the target area, engineers can visualize where noise is stronger and identify potential sources of EMC problems.
7. Is the WM7000 Series useful for EMC troubleshooting?
Yes. The WM7000 Series helps engineers locate electromagnetic noise sources more efficiently. By visualizing noise distribution, it can support EMC countermeasure planning, design verification and troubleshooting before or after formal EMC testing.
8. What size of PCB can be measured?
The measurable size depends on the model. The WM7400 supports scanning areas up to A4 size, while the WM7300 supports larger targets up to A3 size. Customizable measurement areas may also be available depending on specific requirements.
9. Can it measure cables and larger assemblies?
Yes. The WM7300 is suitable for larger printed circuit boards, long cables and larger electronic assemblies that cannot fit within an A4-size scanning area. The appropriate model depends on the size and shape of the measurement target.
10. Why use a desktop noise scanner?
A desktop noise scanner helps engineers identify noise sources visually and efficiently during EMC design and troubleshooting. It can reduce the time needed to locate problem areas and support better EMC countermeasure decisions during development.
