The Keysight 16047A Test Fixture is a precision accessory for high-accuracy impedance characterization of axial and radial lead components. Designed for use with 4-terminal pair LCR meters and impedance analyzers, it delivers repeatable measurements across a wide impedance range using Kelvin contacts. The fixture includes three interchangeable contact insert sets to accommodate axial leads, radial leads, and short radial leads, enabling flexible device testing from DC through 13 MHz.
## Technical Specifications
