The Keysight Agilent E4990A Impedance Analyzer has a frequency range of 20 Hz to 120 MHz. The Keysight Agilent E4990A provides an industry best 0.045% (typical) basic accuracy over a wide impedance range, with a 40 V built-in DC bias source. The equivalent circuit analysis function supports seven different multi-parameter models and helps you to simulate your own equivalent parameter values of components.
