Please leave the measures and considerations regarding antenna radiation emission and noise terminal voltage before certification to Wave Technology!
With the acceleration of machinery, there is a growing trend for EMI (Electro-Magnetic Interference) countermeasures to take up a larger proportion in the product development process. In such a situation, are you having trouble securing an anechoic chamber or engineers for EMI countermeasures and verification?

Applications/Examples of results
(1) Not only can you use a simple radio anechoic chamber to measure radiated emission and noise terminal voltage, but specialized technical staff will also assist with EMI countermeasure considerations. (2) If the results of the countermeasure considerations indicate that a hardware revision is necessary, we will provide a one-stop service from circuit board design to prototype, re-evaluation, and certification testing agency services. (3) By utilizing the electromagnetic wave visualization system, you can easily identify countermeasure points. (4) In noise terminal voltage measurement, by using a power impedance stabilization circuit network that can distinguish between differential mode noise and common mode noise, it is possible to quickly find effective countermeasures.
