The Keysight 16047A is a high-precision test fixture designed for the impedance evaluation of axial and radial leaded components up to 13 MHz. Using a 4-terminal Kelvin contact configuration, it minimizes residual impedance and ensures reliable measurements across a wide range of frequencies and impedances. Its contact tips can be adapted or changed according to the device shape.
