The E4990A and E4991B impedance analysers from Keysight Technologies (formerly Agilent Technologies) are designed for R&D, quality assurance and inspection engineers characterising and evaluating passive electronic components, semiconductor devices and materials.
With the need for lower power consumption and compact equipment on the rise, efficient power converters have become all the more critical, as has knowing the real characteristics of low-loss components during the design phase. Keysight’s new impedance analysers boast the measurement accuracy to evaluate components from milliohm to megaohm over the 20 Hz to 3 GHz frequency range, and to uncover the real characteristics of high-quality components.
The E4990A offers 0,045% basic accuracy over a wide impedance range, while the E4991B offers 0,65% and features accurate material measurement options that include temperature characteristic analysis from -55 to 150°C and direct read function of permittivity and permeability.
The E4990A has a frequency range of 20 Hz to 10/20/30/50/120 MHz and replaces the 4294A model. The E4991B has a frequency range of 1 MHz to 500 MHz or 1 GHz/3 GHz and replaces the E4991A. The instruments support a variety of Keysight test accessories, making measurement of different applications simple and reliable.
Other key features of the analysers include a compact body that allows them to share desk space with other devices and tools, and a user-friendly interface. The 10,4” colour LCD with touch screen and multiple-setting functions enables users to evaluate many parameters under various conditions at the same time. A sophisticated, equivalent circuit-analysis function supports seven different multi-parameter models and allows users to simulate their own equivalent parameter values for components.
