Sometimes the 'scale' function needs to be reset to 1:1. Bob

This is correct. 8 contains a series capacitor. This is an isolator at low frequency.

Quite right, whatever impedance but no signal in on CH1 will show 50 ohm. Thanks. /Torbjorn

Yes. The other ones are OK.

Hugen - Nice work. I am looking forward to working with the improved version. On the alibaba page, the four inch model is the more expensive of the two listed, correct? Cheers, bill

50 ohm on CH1 means no input signal to CH1 as expected -- NanoVNA Wiki: /g/nanovna-users/wiki/home NanoVNA Files: /g/nanovna-users/files Erik, PD0EK

Colin, What You see in blue on the screen is the CH1 Smith Chart and the value off 50 ohm is to best of my knowledge the input impedance of CH1. Switch to Channel 0 reflect and the marker will jump to

Hi Hugen, True, it was sold as an original with the latest software. I soon realized that this was unfortunately not entirely true :-( This was before I discovered this forum and read that there were

From https://github.com/hugen79/NanoVNA-H/tree/F303 Quote..... "NanoVNA is a very compact and portable vector network analyzer created by Mr. TAKAHASHI Tomohiro(edy555), which cost is very low. It is

I have also seen this. Bad calibration kit. In my case the 50 ohm load did not connect well to the nut ring, which caused bad calibration. Order a new one in good quality. Best Soren

You can measure a filter without a tracking generator and do want you desire... of course WHY. In any case, sure. Set your generator to the same level as your vna. Stop the vna sweep so you can do

Hi everyone, Just curious, is there a way to calibrate the output amplitude so that when measuring say a filter I can get it to read the same as a calibrated spectrum analyzer?? Thanks, Ed

I am glad that Hugen finally decides to release the NanoVNA H4 product, based on F303 and 4" LCD. He kept improving the design that I didn't know when he would be satisfied. Besides these two main
