What are the alternative to vnasaver? I got it running fine but discovered that it is painfully slow and it doesn't mark frequency line in small increments.

What I want is something that is fast as the standalone vna so I can do some what ifs regarding antenna tuning for various frequencies and save the results as well. Maybe VNA_QT does that?

My surfing on VNA_QT seems to indicate that I would have to reflash my 5 year old VNA. Plus I don't know if its faster or how easily one can store output files. I've had reasonable luck reflashing other devices so I think I could do it w/o bricking but if VNA_QT isn't faster then its not worth the effort.

I know I shouldn't complain, after all its all free.

Patience, my boy, patience.

You can widen the RBW and VBW for faster scans. But you will lose noise
floor. You can also decrease the number of segments you wish to scan to
increase speed, but you will lose resolution. You can force more rapid
sweep, but you will lose both peak accuracy and reliability and
resolution. You can also try NANOVNA APP as an alternative. The
trade-offs I've mentioned are basic physics and really can't be overridden
without the compromises I noted.

Patience, my boy, patience.

VNA-QT is not a program for your NanoVNA. NanoVNA-QT (VNA View) is the native software for the NanoVNA V2 Plus4 and VNA6000 series.

There are some very old apps for the NanoVNA like NanoVNA Sharp and NanoVNA Mod3 but they were very basic. NanoVNA App is the one I use and it has very nice features. DiSlord and Owen Duffy have made some nice improvements since the original author OneOfEleven stopped working on the project.

NanoVNA Saver scans reasonably fast if you set the frequency range to your band of interest and then calibrate. Here is a video I made for you showing me matching an antenna for the 20M band using a manual tuner. You can see the SWR, Return Loss and Smith Chart change as I rotate the knobs.

Hi Roger Need

Please what is the latest version reference of Dislord modded NANoVNA-App windows program ? If It does have the Z-renormalized function ? Or Z0-renormalized function ??

H4 firmware gives me satisfaction, what we have to expecte more with Nanovna-App ??

Thanks

Nizar,

No I don’t believe Port Z function is in the latest version but check for yourself.
