Implementation of Signal Flow Graph Rules Analysis on Short-Open-Load-Thru Calibration Algorithm

摘要

The error correction procedures are important in VNA calibration measurement in order to achieve accurate performance. By understanding the concept of error correction, the mathematical analysis related to this feature can be applied easily in further investigation. This paper reviews a mathematical analysis of short-open-load-thru (SOLT) calibration algorithm by using signal flow graph rules. In order to understand the concept of error correction represented by signal flow graph rules, the analysis will start with one-port calibration, before proceeding to two-port calibration. Then, it can be implemented to short-open-load-thru (SOLT) calibration algorithm.
