Abstract: A new type of calibration standards is presented, which has the uncalibrated peer-ports terminated to matching impedances such as 50Ω. Terminating peer-ports increases calibration accuracy since the calibration process is less affected by the undesired crosstalk in the error-network that is being calibrated or in the calibration standards themselves. Using the disclosed peer-terminated standards were shown to have less calibration errors over using conventional dual standards. This is applicable to any electrical measurement and calibration, where the calibration standards are designed to simultaneously connect multiple ports.
