Oristo & Rune,
Here is an interesting HP application note.
Refer to pages 7 & 8 for explanation on using different scan steps on specific segments.

More points means more long measurement and more high probability of some

I will try to sort some light-weight filter
I glued nanoVNA shell command Python script:
.. with a bash script to get 100 values at some frequency:
$ cat scanraw100.sh
ch() {
# echo python /g/Gateway/my/nanoVNAsaver/nVcmd.py "$*"
? python /g/Gateway/my/nanoVNAsaver/nVcmd.py "$*"
}
if [ -z "$1" ] ; then
? do="scanraw 1 100000 0 1 1"
else
? do="scanraw 1 $1 0 1 1"
fi
for? (( i=1; i<=100; i++ )); do
? ch "$do"
done
$ sh scanraw100.sh > x100
gnuplot> p 'x100' u 1 w l
gnuplot> load 'png.p'
