t's OK now.
Yes I even had a lot of .s1p files in the directory. So, you gave me the idea to modify one so that there is an |S11| > 1 in
And yes S11.EXE spotted it.
---------------------- ------------------
This program checks Touchstone files
for |S11| > 1. These improper values
may indicate invalid VNA calibration.
File |S11| max # > 1
Test.s1p 1.318561271 1
---------------------- ------------------
In fact S11.EXE seems to test all the *.s1p files present in the directory. It still lacks at least one piece of information produced by
S11.exe -? (for example)
I use many reels I had never encountered such behavior before.
As my files were correct, it came out the very ambiguous message:
---------------------- ------------------
This program checks Touchstone files
for |S11| > 1. These improper values
may indicate invalid VNA calibration.
No files found with |S11| > 1
---------------------- ------------------
This S11.exe does not solve the problems of erratic dots produced by the nanoVNA that nanovna-saver does not filter. We are missing two apps
1/ one, fundamental, which corrects the .cal files to purge/correct them of their aberrant measurements. On this subject no one has proposed a relevant algorithm. Encode, then the application is simpler.
2/ the other which corrects outliers in the .s1p files. It's less serious because you can restart a measurement sequence that will perhaps be faultless.
