Hi, Thanks for your reply. It was not wrong with any setup. The thing is in the direct form option there are only few default options to plot like S11, S21, S12, S33 like that for further ports (for more than 4), there is another option where you can choose the port number from drop down list which I ignored. Thanks a lot though for your reply.Image may be NSFW.
