双六端口网络分析仪的L校准法和系统的测量误差分析
L CALIBRATION FOR DUAL-SIX-PORT NETWORK ANALYZER AND ANALYSIS OF SYSTEM MEASURING ERROR
-
摘要: 本文提出了仅用一段传输线校准双六端口网络分析仪的新方法L校准法。用此方法,传输线电长度无需确知。详细分析了双六端口网络分析仪使用非理想隔离器产生的误差,给出了系统工作于准理想隔离状态所需的隔离度。

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. -
