Calibration of a single reference receiver VNAs for non-insertable devices test

When measuring a non-insertable device using a vector network analyzer, calibration based on eight-term error model such as TRL or SOLR is commonly used. The VNA is in the form of a single reference receiver, and the signals of the two reference receivers cannot be measured simultaneously during calibration. In this paper, we propose a method based on different error models transformation to calculate the switching error terms and realize the eight-term error model calibration of single reference receiver VNAs.
