Product Information

My 'H' model was sold by a chap in Ky and it arrived VERY fast and the 'H' models have a plastic case. Quote from: MadTux on January 28, 2023, 06:13:25 pm Basic NanoVNA-F or H is good enough for learning, NanoVNA-F V2 if you want nice mechanical design, a bit more frequency range and better display. Save the measurement data (optional): To save the measurement data for future reference, tap the ‘Menu’ button, select ‘Save’, and then choose a file slot to save the data.

On initial examination, it appears to work properly, I could slide a piece of paper between case and touch screen so it does not seem to have the problems that plagued earlier models where the screen did not work because of pressure from the case. At the frequencies I’m interested in, medium wave to 30MHz, the length of the crock clip leads won’t affect the test results. Read the SWR measurement: The SWR graph is now displayed on the screen, with the frequency range on the horizontal axis and the SWR values on the vertical axis. version, Nanovna-H4 is added a brand new panel plus added a new SD port for data storage(support up to 32GB memory card, not included in the package).For example, it shows ">DFU" option under CONFIG and of course the NanoVNA_H4 does not use this method to enter DFU mode. I found that it is much easier to use with the various PC software programs that are freely available online. DFU mode is replaced by "Brightness" and I remember to have seen DFU mode passing by, but can't find it back now, please how to entyer DFU mode, I tried a long press af the swith, but no luck. However, as with every piece of test equipment, you have to be careful how you interpret the results.

Given hugen's history I know he will quickly release a firmware fix, but this being the Chinese New Year will likely delay his response.
