The current display is in smith chart with Magnitude and phase, and or on
SWR just that, No R and j. R is the resistive component of the signal and
j is the computed reactive element in ohms of the phase. Yes, we can do it
off line of course, but both of my other VNA units will give me the R and j
directly. Being a RF nut, I don't use Smith charts in the design of
anything I use the R an j. The Smith chart is good for many things, but I
don't use it, I prefer to look at the Magnitude and the j as it is
displayed in a swept response of frequency. That is, I am mostly
interested in the j0 crossover that is the resonance of the load I am
putting into the analyzer.
Example: if I want to know the resonant frequency of a antenna, I do not
look for min SWR. That tells me nothing. Once I know the j0 frequency, I
then can address matching the R magnitude and I am done..... Sorry for the
long comment, but I think it needed to be said. Cheers,
Mel, K6KBE

Hi Martin,
I want to do more things with markers, including having the ability to add
more of them, and/or to change what information is being displayed. Not
sure it will be in the next release, but it's on the list.
I am a little confused, though - my background is not (at all) in RF tech:
Isn't Series R & X = Z? Which is already displayed? Or what are we talking
here?

Hi Rune,
I just tried NanoVNA-Saver 0.1.3.
I think the new enhancements are a great improvement in terms of
usability
and the fixed scaling options help prevent charts 'jumping around' all
over
the place when they auto scale, which make comparisons between plots so
much easier.
Thanks for following up on the suggestions, much appreciated.
Cheeky ask - Any chance of adding Series R & X values to the markers in
the next release :-)
