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

Applications/Examples of results
(1) Not only can you use a simple radio wave anechoic chamber to measure radiated emission and noise terminal voltage, but our 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 provide a one-stop service from circuit board design to prototyping, re-evaluation, and certification testing. (3) By utilizing the electromagnetic wave visualization system, you can easily identify points for countermeasures. (4) In noise terminal voltage measurements, by using a power supply impedance stabilization circuit network that can distinguish between differential mode noise and common mode noise, it is possible to quickly find effective countermeasures.
