Agilent/Keysight 16485A

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.

– Key Features

• Enables connection of multiple component types to impedance measurement instruments
• Improves measurement accuracy and repeatability in impedance analysis workflows
• Supports frequency-dependent characterization across analyzer operating ranges
• Minimizes measurement error through optimized fixture design
• Adapts to various component geometries and material configurations

– Typical Applications

The 16485A serves applications requiring precise impedance evaluation of discrete electronic components, material properties, and component parameter extraction. It is particularly suited for frequency-swept impedance measurements, material loss characterization, and component screening workflows where measurement repeatability and accuracy are critical.

– Compatibility & Integration

The 16485A integrates with Agilent and Keysight impedance analyzers, including the E4991A and 4291A/B platforms. It functions with any impedance analyzer capable of measurements spanning 20 Hz to 3 GHz or 40 Hz to 110 MHz frequency ranges, establishing a standardized interface for DUT connection and measurement acquisition.
