Keysight Technologies E4982A is a high‑frequency RF LCR meter designed for impedance measurements of components using a 1‑port reflection method. It covers up to 3 GHz (frequency‑option dependent) with a 50 Ω coaxial test port and supports standard R/L/C/D/Q and related impedance parameters with calibration via OSL.
