Propagation delay mode cut back type
Free space method
dielectric constant and dielectric loss tangent(Dk/Df)
measurement system

Model No. DPS06
In the range of 500MHz-40GHz this system measures dielectric constant and dielectric loss tangent of the materials which have dielectric constant of 1.05-500.
Especially it greatly contributes to large loss specimens.


Measurement frequency 500MHz~40GHz
Characteristics of specimen Dielectric constant : 1.05~500 Accuracy ±5%
Dielectric loss tangent : 0.001~5
