The Agilent/Keysight 16485A is a test fixture engineered to interface devices under test (DUTs) with impedance analyzers for precise impedance measurement applications. It enables accurate, repeatable characterization of electronic components and materials across a broad frequency spectrum by optimizing the measurement path between the analyzer and DUT. The fixture’s design minimizes measurement error and extends the analytical capability of impedance measurement systems to diverse component types and material evaluations.
Technical Specifications
The 16485A connects to impedance analyzers operating across wide frequency ranges, typically from 20 Hz to 3 GHz depending on the analyzer platform. It accommodates discrete components—capacitors, inductors, and semiconductors—as well as bulk materials for impedance characterization. The fixture utilizes coaxial connectors or specialized 4-terminal-pair connections to establish the measurement interface between analyzer and DUT.
