[SI-LIST] Re: VNA and characterization of long cables

You can always make TDR/TDT measurements to characterize long cables.  See
Tek's IConnect offering.  It will output your Touchstone files from Time
Domain measurements.

Subject: [SI-LIST] VNA and characterization of long cables

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
