Thanks, QRP -
fixed, try this firmware, let me know if it works
Works for me:
$ alias nv
alias nv='python nVargs.py'
$ nv frequencies > freq.txt
$ nv data > data.txt
$ paste freq.txt data.txt > nanoVNA.s1p
$ cp nanoVNA.s1p ../../GitHub/oristo/altervista/gnuplot/
G:\Gateway\GitHub\oristo\altervista\gnuplot>grep s1p plotsmith.p
replot "nanoVNA.s1p" u 2:3 w l title "USB test 50-900000"
gnuplot> load 'plotsmith.p'
