Impedance Analyzers

Real characteristics – achieved only with an impedance analyzer

Only Keysight impedance analyzers provide unparalleled accuracy for component evaluation from mOhm to Mohm, from 5 Hz to 3 GHz. Add an impedance analyzer to your lab and achieve real characteristics of high quality components.

  • The E4990A Impedance Analyzer with a frequency range of 20 Hz to 120 MHz provides an industry best 0.045% (typ.) basic accuracy over a wide impedance range, with a 40 V built-in DC bias source.
  • The E4991B Impedance Analyzer with a frequency range of 1 MHz to 3 GHz provides 0.65% basic accuracy over a wide impedance range, with a 40 V built-in DC bias source (Option 001). Material measurement options provide temperature characteristics analysis capability from -55 °C to 150°C (Option 007) and direct read function of permittivity and permeability (Option 002).
  • The E5061B ENA series network analyzer with option 3L5/005 supports a wide frequency range from 5 Hz to 3 GHz, with 2% (typ.) basic accuracy, 40 V built-in DC bias source, network analysis, impedance analysis and Gain/Phase analysis capabilities.

Select the appropriate frequency range for your application

Keysight’s impedance analyzers provide the best performance in the industry with frequency options to meet your needs at an affordable price. You can select the most appropriate frequency range for your application, from 10 MHz to 3 GHz. Flexible frequency upgrade options are also available.
