Agilent/Keysight 434A

The Agilent/Keysight 434A is a precision LCR meter for measuring inductance (L), capacitance (C), and resistance (R) across component evaluation, quality control, and circuit design workflows. The instrument delivers multi-parameter characterization including dissipation factor (D), quality factor (Q), impedance (|Z|), admittance (|Y|), reactance (X), conductance (G), susceptance (B), and phase angle (θ).
