Hello! I have heard that in practice it's is not possible to to VNA measurements on cables that are around 7 meters long or longer. Can someone explain why is it so? How do we otherwise obtain simulation models of long cables if, they cannot be measured on a VNA and saved in Touchstone format? Thanks! /Mark ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List forum is accessible at: http://tech.groups.yahoo.com/group/si-list List archives are viewable at: //www.freelists.org/archives/si-list Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
