Re: NanoVNA-Saver 0.0.12


 

Hi Bo,
now I've gotten to your long list of ideas! Thanks for providing them!

Screenshot/image saving is definitely interesting! Currently, the
graphs/plots are all painted directly on a Qt widget, so I would have to
find something that could save those. I think it should be possible, though.

Exporting a general frequency/amplitude (or even amplitude/frequency) file
shouldn't be much of an issue. But, maybe it relates to your next
suggestion: The auto markers for filters. I'd *love* to do that! My biggest
issue is finding a way to 1) identify the filter, 2) find out what the
passband is, and what the passband level/ripple is, and then identify the
3dB/10dB etc. points. The latter part, finding the points, is "easy". What
worries me is the first part :-)

The marker architecture is fully set up to allow for more than 3 markers -
but to fit in 1366x768, it's currently limited to 3. I think I'll add it as
a setting so you can have more. :-)

Thicker trace lines should be an easy setting to make.

The cosmetic points are all sensible, and I'll endeavour to have them
included soon! The only exception is the COM port bit: The current
functionality already finds the correct device if possible, so a dropdown
menu would only really be required if you have more than 1 NanoVNA
connected... I don't think I'll present the users with devices that the
software can't identify as compatible, for now at least, but maybe the
connection functionality needs an overhaul at some point.

Segments: This was previously called sweep count, and is really the base
functionality of the software, the sole reason I wrote it: It refers to how
many segments the sweep span is broken into, each of 101 sample points, in
order to increase resolution over the default the NanoVNA provides. So
putting in 10 provides 1010 points, 50 gives 5050 points, etc. The label
next to it presents the distance between each data point, as that's proven
useful for me, at least. Hz/step is my term for the number of Hz between
two data points .. maybe that's just my own terminology bleeding through, I
don't know. I'm open to suggestions :-)

Thanks again for taking the time to write out all these suggestions!

Hi

I am relatively new to the NanoVNA thus the NanoVNA-Saver but I have spent
a number of hours in front of an 8753C :-) I really like the NanoVNA-Saver
and therefore have some ideas for further improvements. If I didn't like it
I wouldn't even bother to make suggestions :-D

Ideas rel. to 0.0.12
- make it possible to save the full NanoVNA-Saver window and/or each plot
without having to do a screen dump via another tool
- It would be ideal if there is a save dialog with an input field that is
used as preamble in the file name(s) and/or also for caption in the
pictures. In the file name please use underscore instead of spaces
- the dialog box could have check boxes for which pictures to save,
perhaps even a check box for adding a time stamp YYYYMMDD_HHMM to the file
name(s)

- in addition to the S-parameter files also to have a set of files for
plain amplitude/attenuation vs. frequency

- x dB auto markers, e.g. 1 dB, 3 dB, 6 dB, 30 dB, 60 dB is difficult in
general on the NanoVNA, and buttons for finding these points on LPF, HPF,
BPF and Notch fillters
- more than three markers in general

Cosmetics
- the lines on my monitor are rather thin. It might be related to my
screen resolution being 2560 x 1440 pixels on a 32" monitor. But it might
be an idea to allow for thicker traces lines
- reduce the number of decimals, e.g. fF and pH resolutions are not
important
- there is a missing space between the impedance value and the Ohm-symbol,
1234.5ohm-symbol -> 1234.5 ohm-symbol (ISO 80000)
- there is a missing space between the band value and the meter, 2200m ->
2200 m (ISO 80000)
- show the marker color in the caption of the marker value panes
- auto 1000 separators on frequency input boxes
- COM port dropdown box listing COM-ports and the logical names if
available. It will make it easier to find the device. Perhaps even auto
connect if logical name is found

Segments
- I am not sure I understand "segments", however, I do understand points
which might be an old habit. The Hz/step unit of the segments is confusing
to me
