Keysight Agilent HP 4291A

4291A Agilent Impedance Analyzer

RF Impedance / Material Analyzer

The 4291A 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 4291A Features:

  • Basic accuracy of 0.8%
  • Internal generator sweeps from 1 MHz to 1.8 GHz with 1 mHz resolution
  • Gain-Phase measurements include amplitude, phase, and group delay
  • Impedance measurements include |Z|, |Y|, phase, R, X, G, B, Lp, Ls, Cp, Cs, D, Q, deviation, and deviation %
  • DC bias to ±35 V
  • GPIB

The Keysight Agilent HP 4291A uses a direct current-voltage measurement technique, opposing the reflection measurement technique, for more accurate impedance measurement over wide impedance range. A 1.8m error-less cable connects the Keysight Agilent HP 4291A analyzer to a test station so you can extend your test point away from the analyzer without losing accuracy. Advanced calibration and error compensation function eliminate measurement error factorsw in fixtures and assure high accuracy and repeatability at DUT/MUT.
