Impedance Analyser, 20Hz to 120MHz

Manufacturer's part number :


Manufacturer Agilent Technologies

Keysight Technologies

Description :

The E4990A Impedance Analyser has a frequency range of 20 Hz to 120 MHz. The 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. Five frequency options (20 Hz to 10/20/30/50/120 MHz) and frequency upgrades allow you to choose the most appropriate option with the latest amount of investment.

Whether you are in R&D, QA, or inspection, the E4990A is an ideal solution for characterizing and evaluating electronic components, semiconductor devices and materials.
