The 3.1 hardware version also offers the choice of 3 push buttons or a single thumb-wheel. The NanoVNA-H4 looks like it will actually give usable performance to 2 GHz if the firmware limits are opened up.Ī new hardware 3.1 version of the NanoVNA-F has just been released for sell with an improved RF bridge, which may match the NanoVNA-H4's performance above 1.5 GHz. If you are only going to make measurements up to 1 GHz then you'll be happy with either unit. They each operate from 10kHz - 1.5GHz with their current firmware, although the performance of the NanoVNA-F starts to get iffy above 1.3 GHz. I own both models and I am happy with either. Both the NanoVNA-H4 and NanoVNA-F already incorporate identical out-of-the-box TDR measurement capability. 'I would like to use TDR one day, any clue if a version running it will be released soon?' This user group beats the NanoVNA-F user group hands down when it comes to support, which adds immeasurable value to the NanoVNA-H4. It proves to me that while the NanoVNA-F may be slower at introducing new firmware updates than the NanoVNA-F that the developer is fully capable of keeping up with any worthwhile new features. With firmware release 0.1.1, the NanoVNA-F incorporates pretty much all of edy555's 6.0 firmware improvements and adds a few of its own.

Up until about a month ago I would definitely have said the NanoVNA-H4 was the better developer supported model. 'I would like the 4.3 or 4.0 inch display, but it's look like the F and H4 version are not the same processor, so wich one is the more supported model?'

Displaying data on multiple chart types, such as Smith, LogMag, Phase and VSWR-charts, for both S11 and S21.

Averaging data for better results particularly at higher frequencies.

Splitting a frequency range into multiple segments to increase resolution (up to >10k points).

Reading data from a NanoVNA - Compatible devices: NanoVNA V1 and V2.

Main development is currently done on Linux (Mint 20.3 Cinnamon) The software was written in Python on Windows, using Pycharm, and the modules PyQT5, numpy, scipy and pyserial. This software connects to a NanoVNA and extracts the data for display on a computer and allows saving the sweep data to Touchstone files. Broberg and supports both V1 and V2 hardware.
