[EMC] Local Electromagnetic Wave Irradiation Probe
If you fail the EMS immunity test, it is possible to evaluate where the electromagnetic waves have entered (you can gain hints for resolving the issue!).
MT-676 Series Local Electromagnetic Wave Irradiation Probe - Adopted by automotive electronics development companies and EMC consulting firms - Possible to obtain hints for solutions if immunity tests fail - Identification (estimation) of vulnerable components and circuits that lead to malfunctions - Using a spectrum analyzer with a tracking generator as a signal source - Capable of acquiring the frequency profile of electromagnetic wave intrusion from external sources all at once - Causes of malfunctions can be separated into electric fields/magnetic fields This product was originally developed for research purposes related to "cryptographic security side-channel attacks, fault attacks" and "anti-tamper technology against implementation attacks." It is widely adopted by universities and research institutions both domestically and internationally. (It is used to evaluate the "vulnerability" where cryptographic keys can be deciphered due to malfunctions caused by "electromagnetic wave irradiation," one type of fault attack.) ElectroMagnetic Analysis and Fault Injection (EM Injection) onto Secure Circuits
basic information
- Attach to the EMC noise scanner and execute the scan with the electromagnetic wave irradiation probe. - Use the TG (Tracking Generator) of the spectrum analyzer as the signal source. - Measure a wide bandwidth at once and visualize the intrusion intensity distribution by frequency. - Identify vulnerable components that are the cause of malfunctions and obtain information on factors such as the circuit board. - Frequency: Magnetic field/Electric field irradiation 100kHz to 2GHz typ. - Maximum input: 10W (pulse burst wave)

Delivery Time
Model number/Brand name
MT-676H (Magnetic Field Irradiation) / MT-676E (Electric Field Irradiation)
Applications/Examples of results
- Visualization of electromagnetic wave intrusion intensity (path) for magnetic field/electric field - Identification (estimation) of vulnerable components and circuits that lead to malfunctions - Side-channel attacks, fault attacks, Fault Injection (EM Injection)
Detailed information
-
Scanning the electromagnetic wave (in this case, electric field) irradiation probe (X-Y movement) to visualize the resulting intrusion pathways. In this case, the 464MHz signal is penetrating throughout the substrate, which is believed to be a factor causing malfunction. (Substrate resonance)
-
The WM7000 series EMC scanner allows for the overlay of "CAD drawings" and noise maps as a standard feature. The same overlay is possible when using an electromagnetic wave irradiation probe. (Circuit board photo + CAD drawing + noise map)

Morita Tech has been an innovation company since its founding, utilizing four solution capabilities: "5G," "EMC," "Shielding," and "High Frequency," to continuously realize products and technologies that solve challenges in various industrial businesses. In recent years, we have developed a "Compact OTA (Over The Air) Testing Environment" equipped with a short-range transmission and reception device called "Antenna Coupler," which has received great acclaim from telecommunications carriers and local 5G operators, and has been widely adopted in their "labs." In local 5G, it is used as a desktop OTA testing environment and interoperability testing system for the development and verification of base stations and terminals utilizing open source. Additionally, our product lineup includes various solutions as applied products for EMC visualization solutions aimed at achieving carbon neutrality (decarbonized society), such as "visualization of secondary batteries, visualization of partial discharge, and visualization of transient noise." We have four core departments and technologies in-house: "Mechanical and Structural Design," "Electrical Design," "Software Development," and "Manufacturing and QA," and we are fully committed to meeting our customers' expectations and demands while building long-term mutual trust relationships with them.
