The Keysight E4991B offers unparalleled measurement accuracy (0.65% basic accuracy) for evaluating components across a wide impedance range, from 1 MHz to 3 GHz. The analyzer is equipped with precise material measurement options, including temperature characteristic analysis from -55°C to 150°C (option 007) and direct permittivity and permeability reading up to 1 GHz (option 002).
The optional DC bias function (option 001) of the E4991B supplies DC voltage (±40 V) and current bias (±100 mA) across the device under test. This allows engineers to easily observe the behavior of their device under various DC bias conditions without requiring an external DC bias source. A probe station connection kit (option 010) is also available, enabling simple and accurate impedance measurements on wafers and microcomponents up to 3 GHz.
The E4991B impedance analyzer is available in three distinct frequency ranges: 1 MHz to 500 MHz, 1 MHz to 1 GHz, and 1 MHz to 3 GHz, and replaces the industry-leading E4991A. The analyzer's flexible frequency options allow engineers to select precisely what they need for their current application (with minimal investment) and easily upgrade later as new requirements arise.
“Advances in technology often require new devices, making the development of new dielectric and magnetic materials essential,” explained Akira Nukiyama, vice president and general manager of Keysight’s Component Testing Division. “Our E4991B impedance analyzer and material fixtures contribute to the development process by enabling engineers to understand the true characteristics of high-quality devices, materials, and components. This capability, along with its flexible frequency options and affordable price, makes it ideal for characterizing and evaluating passive components, materials, and semiconductor devices.”.
