Uncertainties for 1-kHz capacitance calibrations have been decreased at the National Institute of Standards and Technology (NIST). The improvements are based on frequency-dependence characterization from 1592 Hz to 1 kHz. The relevant measurements and the traceability procedures from the calculable capacitor to the customer calibration are described.
