The Keysight (formerly Agilent) E4980A Precision LCR Meter is an industry-standard benchtop instrument for component and material evaluation. It provides superior accuracy and repeatability from 20 Hz to 2 MHz, featuring a basic impedance accuracy of 0.05% and high-speed measurements down to 5.6 ms. Designed for both R&D and manufacturing environments, the E4980A supports comprehensive measurement parameters, a 201-point list sweep, and extensive PC connectivity. It is highly configurable, with options like Option 001 for 20 Vrms test signals and 40 V DC bias, as well as handler and scanner interfaces to integrate into automated test systems.
