Power calibration for multiport - vector network analyzers (vna)

摘要

Power calibration method for a multiport - vector network analyzer vna (10), comprising the steps of:Performing (22) of a two-port - s - parameters calibration between a first gate of vna (10) and a second gate of the vna (10);Performing (24) a power calibration only to the first gate of vna (10); andDetermining (26) a power which, by means of a first gate of a test object dut (12) is supplied with the first gate of the vna (10) is coupled, on the basis of the two-port - s - parameters calibration, the between a first gate of the vna (10) and a second gate of the vna (10) is carried out, wherein the power calibration only to the first gate of vna (10) is carried out, a reflection coefficient of the first gate of the dut (12) and a detection of a coupled version of a signal produced by the first gate of the vna (10) is received.
