Hi Folks, I am trying to use the Characteristic impedence value that I obtained from the TDR measurements, at TrisePps to calculate the VSWR(I cannot use a network analyser, don't have microprobes). I was going to plug in the Z0 value into reflection coefficient formula and then into VSWR Formula. Do you think that this a right approach to calculate the VSWR. If so how do I account for the VSWR to change with frequency. Thanks for any thoughts.
