Here is a modified NanoVNA software. It allows to resize window. Also I added two new diagrams: Series RLC and Parallel RLC. It shows Rs, Xs, Rp, Xp and |Z|. Also fixed SWR diagram.

If you have 500 Ohm dummy load, please post screenshot of Series RLC for your NanoVNA with 500 ohm dummy load on CH0. Also please write which version of NanoVNA you're using (white / black with shielding / black with no shielding/,,,) and firmware version.

It will be interesting to compare which version is more precise.

Sa far, it's my best version of the NanoVNA PC soft to use. The max screen options works not optimal, but it is a big adventage against the standard software. I'm verry looking out to the version with the TDR implementation. Grts, on1bes

Here is a new version:
- added TDR VSWR screen
- added Phase Unwrapped screen
- added draft version for Phase Delay screen
- improved live tracking

The phase delay is a draft version, needs to be tested if it works properly.

Good morning all ,
I just downloaded version 2 of the software function tdr is very interesting, the top of the top would be to have a length according to the coefficient of velocity of the coax.

What is your issue? What is unstable in v3? v3 should be much more stable.

Hello Erik ?
In our Radio Club we have different people with the NanoVNA. The NanoVNA extensions are more than welcome. The RESET with Calibration and the screen dump are especially useful. I did a quick test in Win10 and it works well. I only found one bug, but it was already in the previous version:
After connecting you do Get data. Screen is then Logmag S11 & S21. The 2 curves are visible.
Then choose Chart format: VSWR S11. The screen is then blank. If you now click on the lower Auto (Y Min), the program will stop and with an error message:
"An unhandled exception has occurred in the application ...."
"Axis object - the minimum value of the axis is higher than the highest value for a data point."
This error is always reproducible.
You must always close the Software and restart it.
This is a translation. I only have the error message in Dutch.

thanks for the report. I can reproduce this issue. You can avoid this error by setting higher Auto (Y Max) first. I will fix it soon.
