I have a touchtone file from HFSS with following format:

# GHZ S MA R 50

I want below format:

# HZ S MA R 50

I have HFSS design  available. The touchtone file generated is very big from HFSS. I can manually scale the frequency but that might not still 1-to-1 compatible between 2 formats. How can we get this format from HFSS results- solution data? Is there any intermediate tool like ADS can convert? This 2 formats are  significantly different for TDR plots  in another tool.

The Touchstone file format standard allows for different units (Hz, kHz, MHz, GHz) to be used in the file given the appropriate matching header. - The file output by HFSS with unites specified in [GHz] should be able to be read / utilized in any third-party tools which properly implement the Touchstone file standard.

If needing to convert the frequency units from [GHz] to [Hz], then I would reccomend writing a simple Matlab or python script to do this. - Touchstone files are ASCII text files which are straightforward to open, edit, and re-save. - An LLM tool like ChatGPT can generate a script to accomplish this task, however this is outside the scope of Ansys support.
