STB8839 Series Precision Impedance Analyzer

STB8839 series precision impedance analyzer is a new generation impedance test instrument by adopting the current international advanced automatic balance bridge principle. Its basic accuracy of 0.05%, the fastest test speed of 5.6ms, the frequency range of 20Hz-10MHz, and the impedance test range of up to 1GΩ can meet the testing requirements of components and materials, especially for low-loss (D) capacitors and high-quality Measurement of Factor (Q) Inductors. The four-terminal pair port configuration method can effectively eliminate the influence of the electromagnetic coupling of the test line and expand the lower limit of the low-impedance test capability ten times lower than that of the conventional five-terminal configuration instrument.
STB8839 series supports high-power test conditions of 2V AC test signal and 40V DC bias. The enhanced multi-parameter list sweep/multi-parameter graph analysis capability will help users to expand the ability to fully evaluate components.
STB8839 series is a powerful tool for electronic component design, inspection, quality control and production testing. It can implement various tests such as IEC and MIL standards.
