Abstract
A calibration procedure for correcting two port frequency measurements. Calibration standards are initially connected to port one of a network analyzer and individually measured. This process is repeated with port two of the analyzer. A jumper which is used to bridge ports one and two is then connected to port one. At the far end of the jumper, three references are sequentially connected and the combination of the jumper and the terminations are measured. The raw data measured thus far is then processed to extract the two port electrical parameters of the jumper. The measured jumper is then bridged between ports one and two, and a series of measurements are made. Using the known electrical characteristics of the jumper, an intervening network is completely characterized and the measured SM and actual SA parameters of any device to be tested are relayed.
