1800 caliber corner type waveguide measurement system
Large-scale: S parameter is measured by the sweep method that sets up the microwave absorber of 600 caliber items in a rectangular waveguide of L=11m×1.8m×1.8m (combination/ conditions of performance with absorber unit/ ferrite).
300 caliber corner rectangular waveguide measurement system
The material that clears corner holes of the base 10×10cm eight samples or 10×10cm is inserted in a rectangular waveguide of L=4m×0.3m×0.3m and the amount of the reflection attenuation is measured.
39mmφ/7mmφ coaxial tubing evaluation system
