I put here my log of the installation on Windows but this log is in French. I can send it to you in Word if you want to translate it. http://hobbys.free.fr/ftp/nanovna-saver_installation.pdf At home 2

Are you certain that you have the correct port selected for the NanoVNA? And are you certain that the software on the NanoVNA is reasonably current? -- Sent from my Android device with K-9 Mail.

In about 75 seconds the NanoVNA Saver main screen finally shows up. But when I try to connect to the VNA comm port it quickly times out: NanoVNASaver.Hardware.NanoVNA_2 - ERROR - Timeout reading

There is no problem using the RF Demo kit with any NanoVNA. If you are having calibration problems check the cal loads with a DMM to make sure you have an open, load and short. Calibrate right on the

NanoVNA Saver was written in python and all the necessary files to run are "packaged" in the .exe file. Each one is scanned by the virus scanner and it takes a long time to load because of this. On

I think you'll find if you leave that black window a bit longer, then NanoVNA will load... it's a slow starter, that's all. Mike

I mostly use the box alone. NanoVNA-saver refuses to run on my PC (Win10pro, just gives a black window). I have tried VNA-qt, and the big screen is nice, but -qt lacks some features available on the

My nanoVNA is also from Amazon but it's a nanoVNA-F. I did not sound the difference with your -H. Using the box alone is crazy. I advise you to use it through nanovna-saver. It's a bit of a hassle to

There is no difference in calabration kits except maybe different connectors. Clyde KC7BJE

Respectfully, I think measuring a CM choke is being overly complicated in this discussion. The common mode Z is measured just as if the CM choke was an inductor or capacitor. Either measure it with an

Remember when doing a new calibration, you FIRST must *clear* BEFORE running the new calibration. I can not imagine two units behaving identically in this respect. Dave - W?LEV -- Dave - W?LEV

I purchased a NanoVNA off of Amazon. Seem to work when I got it, but then when I tried to calibrate it I'm able to. I even tried updating the firmware. I exchanged it for another one and this time It

Hello Ed, I have not seen this configuration before (I use the configuration mentioned here: http://www.archaeocosmology.org/eng/baluns.htm#simulation). Any link to an article about this way of

The diagram from Miro F9LR is very generalized. It is not specific for the case where the DUT is a common mode current choke (current balun). It might be helpful to review what a common mode choke is

Well.. you already see the multifunction capability (Spectrum Analyzer, 1 direction VNA) in popular instruments like the Keysight Fieldfox, and similar devices from Anritsu, etc. There will always be
