1. Seamless and Wide Coverage of Bandwidth
The system seamlessly covers a wide bandwidth from 100 kHz to 30 GHz.
2. Measurable Value
The system can provide a wide range of frequency for measuring complex permeability μr' - jμr" (20~30 GHz is available in our measurement service), half-width ΔH, and ferromagnetic resonance relaxation coefficient α (100 MHz~10 GHz) of magnetic materials.
3. Compact device, Simple measurement
With our system, you can achieve a highly accurate measurement simply by making frequency sweep using a vector network analyzer, after setting a sample on the jig.
1) Clear measurement principle --- Reflection method
2) Simple operation method --- Field method, Remove method
3) Compact device --- free transport
At the 11th International Ferrite Conference (abbreviation: ICF11), the system have been awarded the ICF11 New Product & Novel Technology Award.
