4274A Agilent LCR Meter

The 4274A is a 100 kHz LCR Meter from Agilent. An LCR meter is a piece of electronic test equipment that measures inductance (L), capacitance (C), and resistance (R) of electronic components. The LCR meter accurately measures these elements on an electronic device, usually one subjected to an alternating current (AC) voltage source. The LCR meter measures the current through and voltage across the device under test.

The Agilent 4274A is a microprocessor based impedance measuring instrument making the evaluation of LCR components, complex components, and semiconductor materials quick-and-easy. The Agilent 4274A measures only the value of the component and/or device under test, with 5 1/2-digit resolution and 0.1% basic accuracy by reducing the possibility of errors due to self or mutual inductance, stray capacitance and/or residual inductance in the test leads or test fixture used. This measurement is obtained by a four terminal pair configuration and a built in automatic zero offset to compensate for these errors. A self test provides an automatic operational verification check indicating a pass or fail condition.

A wide range of components can be tested with the Agilent 4274A due to its wide frequency range of 100 Hz to 100 kHz and test signal levels of 1 mV to 5 VRMS. The meter measures equivalent series resistance (ESR), impedance (|Z|), phase angle (Theta), reactance (X), susceptance (B), and conductance (G), in addition to the conventional L, C, R, D and Q parameters.
