HP4291 offers wide frequency range of accurate impedance measurement from 1MHz to 1.8GHz. Direct impedance measurement technique uses the new RF I-V method. By using the RF I-V method, the impedance is measured directly from. ratio of voltage and current. The conventional impedance analyzer uses the reflection coefficient method.

The Keysight 4291B RF impedance/material analyzer provides a total solution for high-accuracy and easy measurement of surface-mount components and dielectric/magnetic materials.

For surface-mount component evalua-tion and material testing, the Agilent 4291B Impedance/Material Analyzer is an integrated package designed to provide accurate testing using standard fixtures at frequencies up to 1.8 GHz. The Agilent 4291B and its test features comprise a complete solution for RF com-ponent evaluation and material analysis.
