Hi Gabriel It still looks pretty fine. A S11 dB with e.g. 0.1dB/division will tell you a lot compared to a simulated line in SmithChart. A shorted line does not have the S11 sloping trace the first

One BNC-binding post adapter should be flipped to allow thru calibration without crossed wires

Ok. Then how do you handle calibration and test. Is cal done with the barrel adapter in place? Or do you cal at the vna ports and then electrically de embed the adapter?

Hi Herb, "Pmax, I have not performed any updates (see attachment). Two other users have provided feedback at groups.io of their NanoVNA-H4’s locking up when setting the center frequency above 1.5

This is very interesting, but I hope it is possible to buy from Europe. What kind of calibration standards are good enough. It will be interesting to see how bad some very low cost 2.4G WLAN antennas

Hi, Do please put in a suggestion of accepting Paypal (even if they have to charge us extra). In Europe, some banks are not happy with the buyer passing card details to countries where they are not

Hi, I have just purchased a Nanovna H4 from Hugen's Alibaba store. Very impressed so far with it, but can anyone tell me is it possible to save a configuration? For example, when I switch it on, it

Ken,I think you meant to say in the last paragraph that the MCU can NEVER be bricked as you will always be able to get back into dfu mode.? ... Larry On Fri, 24 Jan 2020 at 10:24 PM, Ken Liao,

Herb, Thank you for helping me test out the firmware. I was using Ubuntu and didn't try it out at Windows. I will be out of reach of my lab computer for the following two days. So it will take a few

Herb, How did you manage to get into DFU mode and reflash if the serial port was not recognized in Windows?

Ken, I used DFU File Manager to convert your hex file to dfu format and then DFU Demo (not File Manger as I previously wrote) was able to load the converted file without error. I encountered the
