A new universal calibration method for four-terminal-pair admittance standards

A universal calibration method for four-terminal-pair (4TP) admittance standards, developed for frequencies up to around 10 MHz, is presented. The method is applicable to calibration of conversion adapters that convert a system from a 4TP to either a three-terminal system or a one-port system. Implementation of the method requires only a set of driving-point-impedance measurements, using proven one-port technology, and calculations of 4TP transfer admittance and output impedances using an impedance matrix.<>
