Keysight Technologies, Inc. has announced shipment of its E4991B impedance analyzer, specifically designed for R&D, quality assurance and inspection engineers characterizing and evaluating passive electronic components, semiconductor devices, dielectric materials and magnetic materials.
Keysight’s E4991B offers unparalleled measurement accuracy (0.65 percent basic accuracy) for evaluating components over a wide impedance range, from 1 MHz to 3 GHz. The analyzer features accurate material measurement options that include temperature characteristics analysis from -55°C to 150°C (Option 007) and direct read function of permittivity and permeability up to 1 GHz (Option 002).
An optional DC bias function, Option 001, can be used with the E4991B to supply DC voltage (± 40 V) and current bias (±100 mA) across the device under test. This allows engineers to observe their device’s behavior under various DC bias conditions without having to use an external DC bias source. A probe station connection kit (Option 010) is also available that enables easy and accurate on-wafer or micro-component impedance measurement up to 3 GHz.
The E4991B impedance analyzer is available in three different frequency ranges: 1 MHz to 500 MHz, 1 MHz to 1 GHz, or 1 MHz to 3 GHz and replaces the industry-standard E4991A. The analyzer’s flexible frequency options allow engineers to select exactly what they need for their application today, with the least amount of investment, and easily upgrade later as the need arises.
“Advances in technology often require new devices and that makes development of new dielectric and magnetic materials essential,” said Akira Nukiyama, vice president and general manager of Keysight’s Component Test Division. “Our E4991B impedance analyzer and material fixtures aid the development process by enabling engineers to uncover the real characteristics of high-quality devices, materials and components. That ability, coupled with its flexible frequency options and affordable pricing, make it ideal for characterizing and evaluating passive components, semiconductor devices and materials.”
