The Agilent/Keysight 4265B is a precision LCR meter engineered for accurate impedance characterization across discrete test frequencies. It measures impedance, admittance, resistance, reactance, conductance, susceptance, capacitance, inductance, dissipation factor, quality factor, and phase angle—supporting both auto and manual readout modes with equivalent circuit modeling.
