Keysight Agilent HP 4191A

4191A Agilent Impedance Analyzer

Impedance Analyzer

The 4191A is an impedance analyzer from Agilent. Electrical impedance analyzers enable the measurement and monitoring of the opposition to current in AC, or alternating current, systems. Impedance refers to how the chemical or physical properties interact with voltages and currents, or how well a component passes current. Use an impedance analyzer to test equipment such as capacitors, inductors, and resistors.

Keysight Agilent HP 4191A Features:

  • 1 to 1,000 MHz variable test frequency with sweep capability
  • Measures 14 parameters with maximum resolution of 4 1/2-digits
  • Internal ±40 VDC bias
  • HP-IB

The Keysight Agilent HP 4191A RF Impedance Analyzer measure 14 parameters with a maximum resolution of 4.5 digits.  The internal synthesizer provides variable frequencies from 1 MHz through 1000 MHz covering the UHF, VHF, and video bands with automatic sweep capability.  An internal dc bias supply with auto sweep function covers the voltage range of ± 40 V in 10 mV steps.

The Keysight Agilent HP 4191A permits reliable measurements over a wide measuring range.  Its outstanding repeatability, frequency response, and accuracy are made possible by a unique error-correction capability and specially designed test fixtures.  These features allow the Agilent 4191A to be used in evaluating electronic materials, components, and circuitry.

The internal synthesizer provides a maximum resolution of 100 Hz (option 002) with an accuracy of 3 ppm, allowing small changes in the resonant frequency of the device under test to be easily detected.  The swept frequency capability aids in the analysis of frequency characteristics of the device.

Two complete front-panel settings (parameter selection and the sweep control) can be stored in a non-volatile memory and recalled at any time with a single key operation.  This, together with the standard HP-IB interface, makes the Keysight Agilent HP 4191A extremely efficient as either a standalone or a systems instrument.
