Low frequency options enhance LCR meter

Posted By : Mick Elliott

Keysight Technologies has added three low-frequency options for its E4982A LCR meter. It makes the instrument well suited for RF inductor, coil and EMI filter manufacturers that are required to perform impedance testing at various frequencies. Today’s smart phones and other electronic equipment often utilise components such as inductors and EMI filters. Ensuring these passive components operate as expected in the real-world requires impedance testing during production, as well as during quality assurance.

The new options allow manufacturers to easily test passive components at desired frequencies. The options cover the 1-MHz to 300-MHz (Opt. 030), 500-MHz (Opt. 050) and 1-GHz (Opt. 100) frequency ranges. These new frequency range options complement the E4982A’s existing 3-GHz measurement capability (Opt. 300). Frequency upgrade options are also available.

“Impedance testing is a critical step in the manufacture of passive components,” said Akira Nukiyama, vice president and general manager of Keysight’s Component Test Division. “Performing this testing cost-effectively is just as critical. With our new low-frequency LCR meter options, manufacturers now have the ability to perform the required testing in a highly cost-effective manner.”

Keysight’s E4982A LCR meter is used in passive component manufacturing where impedance testing is required. The meter features high measurement speed, 0.8 percent basic accuracy with unparalleled measurement repeatability, and a wide impedance measurement range in all frequency options. Its powerful functions make it ideal for use in manufacturing, R&D and quality assurance.
