The Keysight 16197A is a precision test fixture for impedance measurement of surface-mount devices with bottom electrodes. Operating from DC to 3 GHz, this fixture minimizes parasitic effects to deliver repeatable, accurate characterization across broad frequency ranges. It accommodates SMD sizes from 1005 mm (0402 inch) to 3225 mm (1210 inch) in standard configuration, with optional support for smaller 0603 mm (0201 inch) devices. The fixture features interchangeable device guides and electrode plates with selectable spacing of 0.5 mm, 1 mm, 1.5 mm, or 2 mm (0.2 mm with Option 001) to ensure proper contact alignment.
