Keithley 4215-CVU

Using a tool such as the Keithley 4200A-SCS Parameter Analyzer equipped with the optional 4215-CVU Capacitance Voltage Unit (CVU) enables the user to measure a wide range of capacitances, including very low values of capacitance, <1 pF. The CVU is designed with unique circuitry and is controlled by the Clarius+ software to support features and diagnostic tools that ensure the most accurate results. Using this CVU with proper techniques can enable the user to achieve very low capacitance measurements with tens of attofarads (1e-18F) noise levels.
