Keysight (formerly Keysight) LCR meters, capacitance meters and resistance meters, and impedance analysers are useful in testing components and materials in a variety of research and design applications and in component manufacturing.
LCR meters measure impedance (inductance, capacitance, and resistance) at spot frequencies. Capacitance meters measure capacitance at spot frequencies. Resistance meters are optimised for high-resistance or low-resistance measurements. Impedance analyser is the most powerful tool to measure impedance (inductance, capacitance, and resistance) across a range of frequencies.
