I was hoping you would chime in on this thread eventually. Looks very interesting. It seems I should do some software processing after sweeping using my HP4195A. It hss some internal matching, but you have warned that it gets confused about wide-band or narrow-band properties :) > Enjoy Always! :) Cheers, Magnus > Bernd DK1AG > > > -----Ursprüngliche Nachricht----- > Von: time-nuts [mailto:time-nuts-boun...@febo.com] Im Auftrag von Brooke > Clarke > Gesendet: Mittwoch, 23.
