Compact electromagnetic interference measurement system

Model No. EMC01

The anechoic chamber is not required.
It is 1.2m height, 60cm width.
* Feature
Based on 3m method and 10m method, it can be measured without the anechoic chamber. (0.5~26.5GHz)
As the system is vertical type, it is easy to change specimen.
It converts the radiated wave from the measurement specimen into the plane wave with a dielectric lens.
Amplifier in a short distance is not required due to low loss.
The anechoic chamber is not required because of eliminating signals from outside.
It can be measured by plane wave in the short distance, the measurement based on 3m method and 10m method is performed.
Unnecessary electric wave can be observed from which part of the measurement specimen radiation by moving XY stage in the far field.

This method was presented in the conference as below.
