The system effective directivity of vector netsutowakuanaraiza which is proofread and/or effective source port consistent measuring method, the creation mannered null system

摘要

The system effective directivity of the test port (M) of vector netsutowakuanaraiza (N) which is proofread and/or in order to measure effective source port consistency, the precise transmission line (L) which shorts in the exit being connected, complex reflection coefficient is measured with the entrance of the aforementioned precise transmission line (L) in the consecutive point of measurement inside the specified frequency range. It can offer to discrete Fourier transform the complex reflection coefficient line which was measured to that occasion vis-a-vis effective directivity, based zone is removed from the spectrum which was formed furthermore with that. You can obtain the effective direction value line with the opposite Fourier re-conversion which continues.
