The 1422-CB is three-terminal capacitor with shielded coaxial terminals for use in three-terminal measurements. Connection is made via GR-874 connectors. The calibrated direct capacitance is independent of terminal capacitance to ground, and losses are very low.  The current IET catalog number is 1422-9916, but ours is the GenRad version. 1422-CB
