Noise Suppression Sheet Characteristics Evaluation System
[For Near-Field, Electric Wave Absorption Material Measurement System]
Radiation Suppression Ratio(Rrs) Measurement System
Model No. NSS05
Perform measurement without Anechoic Chamber!
NSS05 is a compact(1200mm x 600mm x 600mm) noise suppression characteristics evaluation system to measure Rrs, requiring no anechoic chamber.
- Measurement compliant with 3m-method and 10m-method are performable without anechoic chamber (0.5~26.5GHz).
- Easy exchangeability of samples
- Low attenuation, only a network analyzer is needed.
The electric wave radiated from the sample, converted to plane wave through the dielectric lens, enables your measurement to take place in short distance, with attenuation staying low, eliminating the necessity of additional amplifier.
It also minimizes the interferences of unnecessary electric wave and thus eliminates the necessity of anechoic chamber.
It also allows you to observe the source of unnecessary electric wave radiating from the sample in
far-field by moving the sample on the XY stage.
