Outstanding Features

Measurement in accordance with 3m and 10m methods is possible without an anechoic chamber (0.5~26.5GHz).
Vertical design of thesystem allows easy sample exchange.


The radio wave emitted from the sample is converted into a plane wave using a dielectric lens. Since the measurement can be performed at a short distance, attenuation is minimal, and no additional amplifiers are required.

As a result, there is little influence from external waves, and an anechoic chamber is not necessary.
Since it can measure plane waves even at short distances, measurement can be performed in accordance with the 3m and 10m methods with calibration in advance.

Also, by moving the measurement sample on XY stage, etc., it is possible to observe sources of unwanted radio waves on a sample in the far field.
