Thru-Short-Delay (TSD) calibration technique for one-port measurements

This paper presents a method of vector network analyzer calibration using `Thru-Short-Delay´ for one-port measurements, which is expected to give a comparable accuracy to the TRL technique as it does not accompany cable movements. It uses a one-port VNA (Vector Network Analyzer) to avoid cable movements with `OSL´ (Open-Short-Load) calibration standards, which are widely used for one-port measurements, together with an air line, preferably one giving a 90-degree phase shift.
