Abstract A new method-"L" calibration technique for calibrating the duali-six-port network analyzer is proposed. Usinf this method a section of transmission line is needed only, and its length is not necessary to be known accurately. The measuring errors introduced by non-ideal isolators are discussed, and the degree of isolation needed for the system working in "the quasi-ideal condition" is given.
