Latest LCR meter provides low-frequency impedance testing

Keysight Technologies has introduced three low-frequency options for its E4982A LCR meter. With the new options, the E4982A is well suited to RF inductor, coil and EMI filter manufacturers that are required to perform impedance testing at various frequencies, says the company. Today's smart phones and other electronic equipment often utilize 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. Keysight's new E4982A LCR meter options allow manufacturers to easily test passive components at desired frequencies. The options cover the 1MHz to 300MHz (Opt. 030), 500MHz (Opt. 050) and 1GHz (Opt. 100) frequency ranges. These new frequency range options complement the E4982A's existing 3GHz 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, Component Test Division, Keysight. "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." The 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, says the company.
