Re: Issue with Live USB Ubuntu running NanoVNA-Saver
Hi Ron,
I'm not strong on how to get Python set up, so I trust others who are able
to help to chime in. :-) But, do try the following:
- In "setup.py", change "PyQt5==5.11.2" to just read "PyQt5". This *could*
fix the problem entirely.
- If not, after doing the above, in the folder containing nanovna-saver.py,
run "python3.7 -m pip install ."
I hope one of these works for you ... Do report back if it does! :-)

Requirement already satisfied: pyqt5 in /usr/lib/python3/dist-packages (5.12.1) FWIW, I see this error, but not consistently, on 64-bit Windows 8.1 while running trivial tests of pyqt5 without NanoVNASaver even installed.<<
As a Python newbie, 3 possibilities occur to me: 1) I read that some versions of pyqt5 have been more stable than others 2) Just as Windows uses your %PATH% to find executables, Python has its own equivalent, which may be screwed up, e.g. incompatible versions of stuff being found earlier: import sys
print(sys.path)
3) relative import bug: [ A similar problem can occur in C with #include "foo.h" vs #include <foo.h>, but static C builds force that to be resolved once at build time..]

Re: NanoVNA V2 own build with the results
Great work Erik - very impressive what can be done at home.

For those that need a nanoVNA V2 for tuning their 2GHz antennas there is
no real reason to wait.
If you have a close look at the attached picture you will notice the main
nanoVNA V2 components in a home build.
In the middle back-to-back are two ADF4351 modules. On top of the
aluminium bar on the left is the 0.1MHz till 3GHz bridge and on the right
is a PCB with three IAM81008 mixers dead-bug style. All controlled by an
Arduino zero hiding at the top. Audio goes to a line in of a PC and that is
all you need for a GHz VNA.
With this home build VNA I was able to solve a problem of my home build
2GHz Spectrum Analyzer that is hiding underneath the VNA.
The aluminium bar at the bottom of the picture is actually a 5 resonator
interdigital cavity filter. I have been trying to buy one for a long time
but as I wanted to convert the 2GHz first IF of the SA directly to the
second IF at 10.7MHz I was not able to find one narrow enough and finally
decided to build it myself.
So I first had to build the 35MHz till 3GHz VNA, just like the NanoVNA V2
(although not so portable)
The construction of the cavity filter proved to be doable without any
special tools except a 4mm tap. The aluminium bar for the housing and the
copper rods for the resonators can be bought cheaply per meter.
Tuning the cavity filter proved to be more difficult than expected as
there is absolutely nothing that gets thru if out of tune. So I used a
simple trick that is of interest only for people that want to build their
own cavity filter and now it works!
Center frequency 2019MHz, 2dB bandwith 4MHz. Better than -70dB at 10MHz
offset. Passband attenuation is -7dB
The spectrum analyzer has hardware RBW filters at 300kHz and 30kHz (top
tin box at right) and a log amplifier (top tin box at left) and variable
FFT stitching RBW filters to a minimum resolution of 1Hz. IIP3 is +17dBm
and noise floor at 300kHz BW is around -100dBm.
To prove it is working I added a 0 to 1GHz scan of the spectrum around my
house using a small antenna. You will notice the FM and DAB transmitters
and the rather strong cell phone base stations
Again apologies for the off topic post.

Hi Tom,
the 2m band limit defaults are set correctly for Europe. The bands are all
manageable ("Manage bands" under Display setup) so you can change any
limits that don't fit your particular location. :-)
I'm not sure what you mean by narrow band limits?
Thanks for trying out the software :-)

Correct the 2-meter band frequency limits. It did not seem to like narrow
band limits being selected but I was not able to be more specific on that.
Anxious to try updates.

Hi Jeff,
since 0.0.10 NanoVNA-Saver supports reading MA format as well, using
Hz/kHz/MHz/GHz. :-)
I'll look at DB format as well, which would be required for Elsie.
RFSim seems to use a very minimal header (# MHz MA), which isn't exactly
best practice, but I guess I could make the software put in default values
for those that are missing.
Thanks for the links! :-)

So, for me (and my Matlab-generated files), it would be great if you also

NanoVNA-Saver can already read and save in RI format (I believe). If you
were
to add the reading of files in DB or MA formats, this would require
mathematical conversions. Not difficult, but more code.
Just in case my comment is misinterpreted -- I didn't mean to sound like
I was only pitching adding MHZ and nothing else. I'd recommend adding DB
and MA formats, as the math conversions should be straightforward.

I wrote Jim, W4EME, about implementing S-file data in Elsie. It is there already he told me. However, I get this error when trying to load the file: 2019-09-30 07:53:56,084 - NanoVNASaver.Touchstone - WARNING - Read line without having read header: 3E+08 -.0273661 -94.79335 -89.91359 -7.727735 -89.91359 -7.727735 -1.876088E-02 -108.5768
Attached is the top of an Elsie file.
Perhaps I am doing something wrong when trying with Elsie and RFSim99 files?

Re: Cal-Kit Standards' Definitions
Kurt.
Thanks for these documents, I updated the link as this will work
It helped me to understand some calibration problems w.r.t. reference planes
Erik.

Re: Cal-Kit Standards' Definitions
Mr. Poulsen, very nice pages and work. Great primer explaining reference planes and delays. I think I'm going to have to read it a few times to absorb everything. I hope someone will modify the calibration instructions in the group files section to include your suggestion and reasoning for not using the open load during calibration.

I agree that this is a very active group. I know that many of the topics revolve around NanoVNA-Saver and others are about firmware and further hardware development. All of them about this and future evolutions of the NanoVNA.
