I think the major contributions would be: o network analyzer (VNA?); o calibration jig which will be required to connect coax to the LISN terminals. Other possible contributions such as resolution and repeatability may also need to be considered, even if they are relatively minor. For lower impedance, network analyzers may have relatively large impedance measurement uncertainty: http://www.keysight.com/main/editorial.jspx?cc=ES&lc=spa&ckey=1000002148:epsg:faq&nid=-11143.0.00&id=1000002148:epsg:faq Regards, Tom -- Tomonori Sato <vef00...@nifty.com> URL: http://t-sato.in.coocan.jp - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
