I was wondering about that..... cause I didn't think the H4 was a lot of $$$$ for what it is. So your <SHIFT> finger lags behind your <4> finger? ME TOO!!!!! Mike – KD5KC -- El Paso --

Barry, you are correct in visualizing the SWR circles. You can show SWR and Q plots on the smith chart and compare them to what you measure with the VNA. I need to run now, but here is an example of

Do any NanoVNA firmware or software versions support display of the Smith chart Admittance scale ? If not, is anyone prepared to add it ? It's useful to have for antenna matching problems. -

Either the H4 or the VNA-F with the latest firmware are capable of TDR functional, it is called transform in the menu selection.

You can use this to flash and download the firmware off of it: https://www.st.com/en/development-tools/stsw-stm32080.html#getsoftware-scroll you can use the “upload” to download from the nanovna.

I allready have a nVNA-H and I'm considering buying a second one. It seems to me that it is a new generation coming up (nVNA-2) and I wonder if anyone can tell me how far away it is. I want my new VNA

Thanks to Tipp and Dough ! But I'm still a bit confused. My nVNA is a nVNA-H. Version: 0.4.5-1-gfbbceca. It does not work with the Getscreen dump software I have downloaded and examined at the

Hi Fred, Yes, the H$ will do this. Alan Wolke (W2AEW) has a very informative youtube video on how to do this: https://youtu.be/9thbTC8-JtA Hope this helps, Steve

This is just a curious question. I can't seem to find any advertising that states this. If it does not is there one of the 4" display models that will do a TDR function? Thanks Fred - N4CLA

If you use an aftermarket case you can drill a hole to run the lanyard attach through as shown in one pic. Or you could attach the lanyard behind a connector on the SMA port also shown -- 73 es God

Yes... and No. Check your email OM.

A Smith Chart has on the horizontal axis the real part of the reflection coefficient from -1 to +1, with zero being in the centre. The vertical axis is the imaginary part of the reflection

I meant to add; I saw that comment from another poster regarding RL being positive and considered responding, but thought it silly. But since you referred to it again I thought it important to

Return Loss, as I know and use it, has always been a negative quantity. Mainly because it is a level returned which is less than the reference used to generate the return signal. Perhaps more subtly,
