Propagation delay mode cut back type
coaxial tube method
dielectric constant and dielectric loss tangent measurement system

Catalog No. dps05002981027-10

In the range of 45MHz-40GHz this system measures dielectric constant, dielectric loss tangent of liquids which have dielectric constant of 1.05-500.
And it can evaluate voltage dependence such as the liquid crystals, by impressing the bias to this system.
