Re: NanoVNA-Saver 0.0.12
Hi I am relatively new to the NanoVNA thus the NanoVNA-Saver but I have spent a number of hours in front of an 8753C :-) I really like the NanoVNA-Saver and therefore have some ideas for further

Re: Experimental 256 point FFT Firmware
qrp.ddc, You are absolutely wrong in saying TDR on the NanoVNA is a 'waste of time'. This is essentially an Amateur Radio hobby forum. Amateurs have been at the forefront of many new innovations in

Re: Experimental 256 point FFT Firmware
more FFT size leads to better time resolution. I don't need to measure cable length with TDR, this is not reliable way, because it depends on cable velocity factor which may vary even through cable

Hi Norbert, Thanks for testing the new functionality! The warnings are normal, sadly, and really just show how the data from the NanoVNA sometimes shows up very corrupted on the PC. I don't know what

Re: How to measure source impedance?
max efficiency happens when you match output impedance with the load on the output connector. More hot on the load means better match and better efficiency. This is pretty easy. For maximum efficiency

Re: NanoVNA-Saver 0.0.12
Hi Nick, the scaling of the R+jX axes works for me - make sure you switch it from "automatic" to "fixed"; otherwise, it won't take effect. If you still have problems, I might need to have a further
