Method and apparatus for calibrating a measuring device path, and means for measuring the s - parameters of a test device in the calibrated measuring device path

摘要

A method for calibrating a first and a second adapter, comprising the steps of:Calibrating (801) of coaxial ports of a vector network analyzer of the workpiece, on which can be led back standards,Switching (802) of a symmetrical by gear circuit path (102) between the coaxial ports, wherein the output circuit by means of a cascaded combination of a first and a second circuit path by means of gear adapter, wherein said first circuit path by means of gear adapter passively and substantially identical to the second circuit path adapter by means of gear, wherein, a measuring device path (104) a first and a second adapter, which are not arranged in a cascading manner, wherein the gear circuit path (102) and the measuring device path (104) substantially equivalent s - parameters have,Measuring (802) of s - parameters of the circuit path (102 by gear),Characterize (803) of the first and the second adapter on the basis of the s - parameters.
