It would be nice if it had come to the fore but sadly Not here in the Uk. Ps I’m absolutely shot after my visit to the local Hospital with my chronic Condition Cheers Roger

I think there is a generic problem that surrounds these well mad pieces of Equipment an that is essentially No operating instructions put in the Box like mine was , it would undoubtedly make a huge

I, too, have compared the original NANOVNA, the -F, and the -H4 to the HP 8753C VNA with the 85047 S-Parameter Test Set. For $50 to $120, HP/Agilent/Keysite/R&S/MFJ/Rig Expert/........ should be

I'm very impressed with the nVNA - good accuracy for just a few $, even at the upper limit of its range: https://ae5x.blogspot.com/2020/04/nanovna-h-vs-keysight-fieldfox-at-1-ghz.html -- John AE5X

As i see on my osciloscope si5351 generate correct freq on 3.2-10kHz, then i measure attenuator its show correct result on lower freq range Measure capacitor also show normal result (yes exist noise

Thanks I think I got it. Have to spend more time on it, and no I did not download the file for the instructions, I will have to that. THANKS!

Turn on your traces and markers. Did you download the manual that I edit from the files section of the forum? It talks about everything and how to set it all up.

I just got my NanoVNA today and I looked around here for the problem I am having, but found nothing. I do not get any digital display at the top of the screen. I have reset it and calibrated numerous

Over the years I've outfitted several small hard cases for various things, and found the best way to do it is half-inch foam rubber carpet padding. First, cut and glue the padding to the entire inside
