Tips for using ISD
The ISD User's Guide offers the following guidelines to get the most out of ISD:
1. The Touchstone files must have enough number of points.
The minimum required is at least two points for every 90 degree phase angle
change in insertion loss (or 8 points per wavelength).
2. The "2x Thru’s" return loss must be smaller than its insertion loss.
3. The "2x Thru’s" insertion loss must be relatively linear, with a few wavelengths at
the highest frequency.
4. Use a 4-port "2x Thru" if strong far-end crosstalk (FEXT) is present.
5. Use a
complete
DUT w. fixture file for extraction.
