Hi,
It would be easy to help, if you could post your .csv file.

If your data has frequency unit GHz and data in real imaginary format, with 50 Ohm reference impedance, this is the header line:

# GHZ S RI R 50.00000

If your data has frequeny unit Hz, use HZ instead of GHZ

If your data is in linear magnitude/angle format, use MA instead of RI
If your data is in dB/angle format, use DB instead of RI

Then, the next lines contain frequency and data pairs (real/imag or magnitude/angle) for S11, S21, S12, S22

Example:

# GHZ S DB R 50.00000
