Dear Friends,
I saw a similar thread, but no solution yet.

I am using Windows 10, 64-bit. I tried with Win-7 as well. In both cases applying calibration crashes the windows application.

Tried with running as administration too, even then it crashes abruptly.

Anyone, please help. I am using NanoVNA 2_2

Regards
MotoG

This is happening with SOLT (modified). Only in this option I could perform
2 port calibration.

The moment I click Apply button, the GUI closes abruptly.

Any way out? Please help!

Thanks in advance💐😊

Hello on the Nano QT- only the SOL and the SOLT work for the calibration the
other don't work with the NanoVNA.

See attaches picture.

Thank you for your reply.

So how can we do 2 port calibration?

SOLT shows only 1 port
SOLT (modified) has the option for 2 port full calibration.

Even the Device GUI, there is no 2 port option.

Any other solution? Please let me know.

Kind regards

Good morning to the group:
I am new to both the VNA as well as the group. A question; is there a step by step instruction sheet, which one can follow and succeed? I am not a PROGRAMMER nor am I a computer wizard.
Thanks ahead for a positive answer.

Hello, the the NanoVNA QT- is one adapted software GUI from one other DIY VNA
project **https://www.kickstarter.com/projects/1759352588/xavna-a-full-
featured-low-cost-two-port-vna**.

The NanoVNA V2/plus not is one full 2 port VNA, the only calibration with this
software is the SOL and the SOLT funcion, the other funcion not work.

For a 2-port 1-path VNA,both the reflected and transmitted signal (S11 and
S21) can be measured, however, the DUT must be physically reversed to measure
the reverse parameters (S22 and S12).

Best regards.

Francesco.

Jay,  These NanoVNAs can only source from port 1, but they can measure at both ports.  So, you can only measure S11 and S21, reflection to port 1 and thru to port 2.  This is thus not a full two port VNA.  To measure S22 and S12, you can reverse the device under test.  For full 2 port calibration with all four S parameters, you would need to install a transfer switch and use software that supports controlling the switch (such as the software from Joe Smith).

Francesco,  Absolutely true.  Only one path.  However, if you can find a high quality transfer switch and make a suitable driver, Joe Smith's software can control the switch via serial port and perform a full 2-port calibration through the switch so you have a full 2-port VNA, perhaps with some loss of dynamic range and accuracy due to crosstalk in the switch.

Thanks, I’ll check it out.
Peter

Yes I make one with 2 HP transfer relay the NanoVNA SSA v.2 is on the same
box, I use with the PC the use of 2 swich relay is better option, the HP on is
VNA use the two relay system for better isolation and less of cross talk for
the connection I use semi-rigid coax cable.

On the attacced file one test of one 1.2 Ghz filter with Joe Smith's
software.

Hello Dave, I suppose the new version work on Win11, **first** download LabViu
and install, restart the pc and **second daunload** the NanoVNA Solver64 .

**Please read the instruction on NanoVNA solver end watch the video before the
installation.**

Regards.

Installing Joe Smith’s software for the NanoVNA V2Plus

Install 7-zip  (free)

Download all 21  NanoVNA_V2Plus_Installer.zip.nnn files from here:

https://github.com/joeqsmith/NanoVNA_Software/releases/tag/0.10

open NanoVNA_V2Plus_Installer.zip.001 with 7-zip (all 21 installer zip files will then be extracted).

Run the installer.  You will then have version 1 installed at C:\Program Files (x86)\NanoVNA_V2Plus

Confirm that it works, than get the latest version of the exe at:

https://github.com/joeqsmith/NanoVNA_Software/blob/NanoVNA_V2Plus/NanoVNA_V2Plus_2p08.zip

Replace the version 1 NanoVNA_V2Plus.exe in C:\Program Files (x86)\NanoVNA_V2Plus

with new version exe.

I suggest that you use caution:  Note that NanoVNASolver64 r3 is different from NanoVNAPlus_r2_08.  It is in development and not supported, no installer and no documentation.  However, it does work. It requires the 64 bit LabView runtime engine and compatible NI VISA but no need for the full LabView program (like Community edition).  The NanoVNAPlus is 32 bit LabView 2011 runtime and is recommended.   Joe Smith indicated that he has halted future development on Solver64 due to new licensing requirements from NI.  Note also there are two different branches for the 32 bit, one for the Plus 4 and one for the smaller hardware.

yes I use the 32bit and the 64bit the NanoVNA Solver 32 is on the pipiline for
the licence problem

David,  The software Francesso is showing in his photo is for the NanaVNA V2 Plus4. Is that the instrument that you have?  Francesco has built it into a very nice instrument using an HP enclosure and relays to make a true two port full S parameter analyzer. I assume that Francesco is using the Joe Smith software because it supports the transfer switch relays.  Unless you intent to add a transfer switch you probably don't need that software (but the GUI is slick).  The open source software VNA_qt will likely meet your immediate needs. Joe Smith would probably discourage you from using it unless you are specific needs or are an experienced VNAuser.   If you want to try installing it, just follow the instructions I posted previously.

Thanks for replies Fransesco and Bob and others input ,I think I'll wait ,I do ok with my antennas using Nano-Qt software , 73 Dave

This has happened to me also.
I managed to finally trap an error message - from Windows - which basically
said it timed out waiting for some kind of registration or model
information.
Timeout settings were clearly too short, or the info did not exist. We are
using a serial port connection - so delays are to be expected.
