We recently overhauled the calibration service for the frequency dependence of four-terminal pair air capacitors provided by the National Institute of Standards
A digital four-arm bridge for the comparison of resistance with capacitance has been designed and demonstrated. The digital bridge mimics the classical quad

Traditionally, vector network analyzer (VNA) measurements have been used to determine the frequency dependence of four terminal pair air capacitors. Recently

Expanding on our previous work on four terminal-pair air capacitors, we present a model for the frequency-dependent capacitance of ceramic capacitors for values

This paper reports our effort to improve a digital impedance bridge. The limit of the bridge resolution and stability is less than 3 parts in 10^9 for the
