Hello Marcus, I did try the constellation sink approach. The result seemed to be scatter plot without a solid trigger lock. A trigger may not work because the Y complex waveform provides no repeating pattern. At this point, I think I could achieve faster results by writing my own code rather than using python and gnuradio for the VNA project. Using Delphi, I could easily use the Ettus DLL. I have been using Delphi since it's beginning and speed has always been my priority. Delphi generates compiled code and runs FAST! Even faster than C++ compiled code that I have run speed comparisons. Also no need for QT.
Thank you for your follow up response, I appreciate your suggestion.
