Datasheet

The Keysight E4990A Impedance Analyzer has a frequency range of 20 Hz to 120 MHz and provides an industry best 0.045% (typical) basic accuracy over a wide impedance range, with a 40 V built-in DC bias source. The Keysight E4990A's equivalent circuit analysis function supports seven different multi-parameter models and helps you to simulate your own equivalent parameter values of components. Five frequency options (20 Hz to 10/20/30/50/120 MHz) and frequency upgrades allow you to choose the most appropriate Keysight E4990A option. With option 001, which enhances measurement speed, the low-frequency (10M/20M/30M/50M) models of the E4990A are as fast as the flagship 120-MHz E4990A model. It’s suitable to reduce overall cost-of-test for accurate evaluation like resonators or inductors or incoming inspection where many points per device or many DUT measurements are required.
