Real characteristics – achieved only with an impedance analyzer

Only Keysight impedance analyzers provide unparalleled accuracy for component evaluation from mmohm to Mohm, from 5 Hz to 3 GHz. Leverage Keysight's impedance measurement expertise to your lab and achieve real characteristics of high quality components.

  • The E4990A Impedance Analyzer (20 Hz to 120 MHz frequency range) provides industry-best basic accuracy of 0.045% (typical) over a wide impedance range, with a 40-V built-in DC bias source.
  • The E4991B Impedance Analyzer (1 MHz to 3 GHz frequency range) provides basic accuracy of 0.65% over a wide impedance range, with a 40-V built-in DC bias source (Option 001). Material measurement options enable temperature characteristics analysis 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 basic accuracy of 2% (typical), 40-V built-in DC bias source, network analysis, impedance analysis, and gain/phase analysis capabilities.
