I just released NanoVNA-Saver 0.1.3! https://github.com/mihtjel/nanovna-saver/releases/latest This release adds a couple of much requested features: Popout charts All charts can now be popped out as

I've been thinking about a test jig for measuring capacitors and inductors. Ideally, this would have built in calibration modes and support all three DUT measurement configurations with the VNA.

Hi Sala, Some test jig ideas can be found here: https://www.kn5l.net/RfAmp/CeTf/ I found if leads are pushed into the breadboard hard enough, they will short to foil. Better to flip single sided PWB.

"I measured a simple class A common emitter amplifier and theory and test results do not match." Beware of signal levels, especially when measuring active devices. Regards, Martin - G8JNJ

By the time you get the boards made and get the connectors, you have spent at least as much as Marcus is asking. He has done the research and gotten the line section correct for the board material.

The windows operating system needs an STMicroelectronics driver installed. 'DfuSeDemo.exe' installed for me in a folder that also includes a 'Driver' folder, in which are folders for Win7-10, in each

Can't see why it is off topic. Much of the calibration is about test jigs or extensions of the reference plane. See hash tag #test-jigs. BTW, hashtags are active in this group. BUT they can only be

I measured a simple class A common emitter amplifier and theory and test results do not match. So, it will be fun and interesting to measure some amplifiers. Have you ideas for test jigs What to

There is a how-to, linked in Wiki Application Notes: http://ormpoa.altervista.org/gnuplot/ Non-interactively, after downloading the four *.p files from above: * One time only, to generate gridpoint

Hello Gyula I also have Rune's fantastic application running on a 32 bit Windows7 machine but battled to get running on a 32bit version of Ubunu (latest LTS v18) and after a remote session with Ohan

Hi Gyula, you're right, the software works fine without 64 bit hardware. The downloadable executable from GitHub also works with Windows 7 32 bit. However, PyQt5 is not available from pip for 32 bit

Hi, I have Python 3.7.4 installed on win7-32 bit SP1 integrated, which runs the nanovna saver. Of course, the required modules are installed with the -pip command, and I have verified that they are

Hi Bryan, thank you very much! :D I'll sit down this evening and read through your explanation more thoroughly than this morning's coffee break allows. But I will comment briefly on the crashes: If

The nanoVNA is a full three mixer three receiver VNA without the switch to reverse the signal path

Hi Paul, great to hear that it runs on Fedora :D Thanks for trying out the software, and for helping other users get it running as well! -- Rune / 5Q5R

You are obviously a much more competent gnuplot user than me. I like it the fact that I can use it non-interactively. The calibration kits I sell come with about 10 graphs showing various plots such

Rune, Yes, your software can do a lot of things that I seem to need. Thanks, again, for continuing to work on this effort. You and your efforts are greatly

Thanks, Larry. I've tried these steps many times with no success. Let me trace the path I've been taking and see if you can spot where I'm going wrong. I followed your pointer to GenHu site
