Re: NanoVNA-saver 0.2.2. crash

 

@ Peter I0YLI
hello peter, the merit is all who wrote the program, who designed the nanoVNA, the developers ..
We, as users, try to give the most correct feedback possible.
@All
I confirm that the program has no problems for me. There is probably some incompatibility with previous versions but this is resolved by deleting folder "NanoVNASaver" in:"users/AppData/Roaming/
In this way you have the "clean" program as if it were the first installation. At this point do the calibration, apply your preferences and you shouldn't have any more problems.

Hi Jim I don't see where my program starts.

I haven't yet created a shortcut on the desktop or in the Menu for
nanovna-saver. So, I open a terminal in my home directory, then enter

cd nanovna-saver

followed by:

python3.7 nanovna-saver.py

NanoVNA-Saver 2.2 on fresh install of Mint 19.3 Cinnamon

 

It does not work on a fresh install of Mint 19.3 Cinnamon
I did notice that the WIKI no longer claims to be multi platform
but it states it will work with Linux SuSE , and you know I will go find
out.
These are the errors I get:

No problem, Leif.

Re: NanoVNA-saver 0.2.2. crash

 

I just signed on to report the same thing..
I had set my start and stop 144.0000Mhz to 148.000 and 2 sweeps... it exited and I couldn't read what was in the DOS BOX

Treid to do a calibrate ---same 144-148mhz... open, shorted, load, isolation and through It opened an error box and told me 2 calibrations open, short, load, isolation, through were the same at 144.0Mhz,

Advise - would workaround be to revert back to V0.2.1 ????

Re: 1/2 of TDR #tdr

 

Oops - wrong menu in prev mesg.
From the NnoVNA User manual I edit (in the files section):

Time domain operation
The NanoVNA can simulate time domain measurements by signal processing frequency domain data.
Select DISPLAY ¡úTRANSOFRM ¡úTRANSFORM ON to convert measurement data to the time domain. If TRANSFORM ON is enabled (Inverted white text on black background), the measurement data is immediately converted to the time domain and displayed.

Please make sure you've got the latest version of firmware from any of the developers in the forum.
There are links to the developer's release sites at the end of the user manual.

Re: 1/2 of TDR #tdr

 

Why do you have a 1000ps delay? It appears you're not in the TDR mode as I see frequency values at the bottom of the display.

If you get good results from NanovnaSaver, it's not the device.
Remember that the visual display interface GUI on the device is controlled independently from what goes over USB so you've probably set up either your gain or sweep settings incorrectly.
Please ensure you go to the DISPLAY? menu and select MORE... then enable TDR.
You should see start & stop in nS along the bottom of the Nano's LCD screen.

Re: 1/2 of TDR #tdr

 

There are now several new features. One seems to be scale for the delay. I have check this, so this may be no problem at all.


1/2 of TDR #tdr

 

I have some 32cm teflon coax with an open end. I see no TDR from NanoVNA but I see a proper TDR from NanoVna_saver 0.22. Frequency settings seem to matter with TDR too. My frequency range was 50k-500M at first and TDR wasn't right. I wish to see TDR from Nano, because it has delay in seconds and not in meters.
I just updated my VNA to 0.54.
I attached a screen capture of delay from Nano.

Not really "all"...I had no clue that a missing driver was the problem: As a tech writer, a problem I encountered often when those who have a lot of experience leave out details needed by the less experienced. Interviewing the "Subject Mater Experts" often required several interviews to get to the meat of the requirements.

As a minimum, including a lead sentence or paragraph about when and why would be a help. Some key words included for searching too, e.g., Not connecting, missing drivers and etc.

Built 0.2.2alpha successfully on 15.12.19 using the instructions here...



Upgraded LM19.2 to LM19.3 on 19.12.19.

It seems to me...

- this is not a nanovna-saver problem
- something may have changed in PyQt5 since 15.12.19
- the upgrade from LM19.2 to LM19.3 may have broken something in the python3.7 installation.

However if I just do this into a clean directory...

$ git clone
$ python3.7 ./nanovna-saver/nanovna-saver.py

then nanovna-saver runs fine, with no "python3.7 -m pip install ."


Re: NanoVNA-Saver v0.2.2 #nanovna-saver

 

Hi Rune,

I still find some strange things in the marker handling? :

1) I did a 2 port calibration? from 10kHz to? 1400MHz (and pressed "apply")

2) I filled all 9 marker-bars with different frequencies from 1MHz to 1400MHz

3) Then I did a sweep with CH0 connected to CH1 by a +/-30 cm long? RG316 cable, that was still connected to the VNA after the through calibration.

4) After this, the markers 1 up to included 5 on the data field were filled with data, the markers 6 up to included 9? were EMPTY. !

5) Marker 4 its color was grey so the tekst above the data field did not show up on the gray background.

6) I tried to change the color, but marker 4 does not accept the new color . (I tried several others and they did)

7) The markers 3 and 4 original frequencies that were set were overwritten both with 100.616536MHz (I had set marker 5 , to 100MHz)

I hope this is of help for this great program.

Kind regards

Jos

The attachments may be of some help. Generally, for HF, 43, 73 or 75
material is used.

Wind your transformer. Properly calibrate the VNA with SOL over the
frequency range of interest - no through is required as you need only a
one-port cal for the measurement. Connect one set of windings to the S11
port. Terminate the other set of windings with a 450-ohm non-inductive
resistor. Measure the side connected to the Port 0 (the S11 port). If
this is 'off scale' or hard to read, try a resistor value half that value.
The impedance transformation will be close to the 450-ohm termination read
with the lower value when 450-ohm terminates the transformer, but may be
easier to real. Things should end up on the right side of the Smith Chart
(the High-Z side).
