Method Overview:

High frequency dielectric constant measurement tester, is an important physical property of various ceramics such as electrical ceramics, device ceramics, capacitors, and composite materials. By measuring the dielectric loss tangent tan δ and dielectric constant (ε), various factors affecting dielectric loss and dielectric constant can be further understood, providing a basis for improving the performance of materials; The basic principle of the instrument is to use high-frequency resonance method and provide universal, multi-purpose, and multi range impedance testing. It uses a single-chip computer as the control of the instrument, and the measurement core adopts frequency digital locking, automatic setting of standard frequency test points, automatic search for resonance points, automatic conversion of Q value range, numerical display and other new technologies. It improves the tuning circuit, reduces the residual inductance of the tuning test circuit, and retains the automatic amplitude stabilization technology in the original Q meter, making the new instrument more convenient to use and the measurement values more accurate. The instrument can measure the Q value of high-frequency inductors or resonant circuits, the inductance and distributed capacitance of inductors, the capacitance and loss tangent of capacitors, the high-frequency dielectric loss of electrical materials, the effective parallel and series resistance of high-frequency circuits, and the characteristic impedance of transmission lines under high testing frequency conditions.

Remarks:

Three different types of instruments, the main difference is the frequency. Choose the appropriate model based on your own testing frequency
