Measurement equipment/system

Model No. DPS08
This system is suitable for a measurement of high loss materials like wave absorber.

This is a closed type measurement system for small size samples and high loss materials. It can measure Permeability(Df) simultaniously. Because of its principle, some space can be made between a sample and jig, so the accuracy may be down. But this method covers unique measurement frequency range.

For making designs of electric wave absorber for far field, we provide a software, with which you can simulate wave absorption ratio according to an actual measurement by one-click Single Layer Type / Multi-layer Type, Electric Wave Absorber, Return Loss Simulation Software Model No. EAS01.

※ As Dk and Df are interacting, when a measurement of them is done simultaniously, the accuracy may not high. If you need highly accurate measurement of Df, please select Magnetic Property Characteristics Measurement System Model No. PER01
