To perform system error correction of a microwave vector network analyzer (VNA), several calibration procedures are applied, several of which are derived from the well-known short-open-load-through (SOLT) calibration method where lumped one-port circ

A method is presented to determine the reflection coefficient of an unknown load by the use of a vector network analyzer (VNA), a known through connection, and only two (or even one) terminations of known high reflection, where load and terminations
