LCR Meter/Impedance Analyzer

MICROTEST LCR/Impedance Analyzer measures the electrical properties of passive components (inductors, capacitors, resistors), including inductance, capacitance, resistance, quality factor, dissipation factor, and impedance.

6632/6632S Impedance Analyzers operate from 10Hz to 50MHz and offer features like sweep analysis, multi-step listings, and Meter mode measurements. They come with built-in measurements of dielectric constant (εr) and magnetic permeability (μr), eliminating manual calculations or extra software. 6632S model supports seven different equivalent circuit models for a faster and more precise understanding of parasitic components' impact on impedance.

For LCR testing, there are high-frequency 6630 series (1M/3M/5M/10M/20M/30M/50MHz) and basic 6360 series (20k/100k/500k/1MHz) options.

6630 series is ideal for automated production line testing, especially for high-speed production, while the 6360 series is suitable for general quality control and incoming material inspection (IQC).

An LCR Meter/Impedance Analyzer can be equipped with a DC Bias Current Source to analyze the magnetic saturation changes in inductors caused by current during operation. The DC bias current source test system provides the 6632/6632S+ and 6350+ series, analyzing and verifying the magnetic saturation current (Isat) and temperature rise current (Irms) of the inductor.
