The Keysight 16047D Direct Coupled Test Fixture enables precise impedance measurements of axial and radial lead components across DC to 40 MHz. It converts the 4-terminal pair configuration of LCR meters and impedance analyzers into a 2-terminal setup for direct device-under-test connection. The fixture delivers accurate, repeatable results suitable for component evaluation and production quality control.
