The Keysight (Agilent) 16346C is a calibration fixture designed to provide traceable impedance standards for impedance analyzers and LCR meters. It enables open, short, and load calibrations while compensating for fixture and cable parasitics. The fixture maintains metrological integrity across research, quality assurance, and production environments by supplying known impedance references that minimize measurement uncertainty contributions from the fixture itself.
