S parameter impedance conversion

I am new to Genesys, I havn't used it yet but when I do, one of the first things I'll have to do involves taking published s parameter device files and converting them from 50 Ohm system impedance to 75 Ohm, as I'm working in the cable TV industry.
I have used Touchstone and MW Office extensively in the past but never with a system impedance other than 50 Ohm. Does Genesys have the capability to automatically convert the impedance of s parameter files?
Thanks, Trevor.

Hello Trevor,

GENESYS is automatic. You don't need to do anything. Load the 50-ohm S-parameter file and just specify 75 ohm ports in your schematic.

If you need a converted S-parameter data file for another application, create a simple schematic with two 75 ohm ports connected to the two-port and export the data. The exported file will be the converted S-parameter data with 75 ohms specified in the file header.

Clear skies and high Q
