The Agilent/Keysight 11604A is a four-terminal (Kelvin) test fixture engineered to deliver accurate resistance and impedance measurements of axial components. By establishing separate current and voltage measurement paths directly to component terminals, the fixture eliminates lead resistance and contact impedance from measurements—critical for high-precision characterization in manufacturing and research environments.
