THRU-REFLECT-LINE - IMPROVED TECHNIQUE FOR CALIBRATING THE DUAL 6-PORT AUTOMATIC NETWORK ANALYZER

In an earlier paper, the use of a “thru-short-delay” (TSD) technique for calibrating the dual six-port automatic network analyzer was described. Another scheme required only a length of precision transmission line and a “calibration circuit.” The better features of these two somewhat different approaches have now been combined and the requirement for either a known short, or a “calibration circuit” eliminated. This paper will develop the theory for this new procedure. Copyright © 1979 by The Institute of Electrical and Electronics Engineers, Inc.
