Re: Cases
Hi, Mike Thanks for the advice, and I will take this on board. I have a general dimensioned drawing of one, and I think when I start looking at possible design¡¯s, I would ask our members to download

Re: Cases
FWIW I haven't printed hagster's design but have printed cases for my two NanoVNAs and one for a friend, based on the design by VK5ZBR. Unfortunately every one had to be different due to physical

Re: Strange readings on my modded vna.
Hi NanoVNAuser Yuo explanation is not very clear and picture a bit fuzzy. But iyt might be you need to introduce a delay via Display/Scale/Electrical delay Kind regard Kurt -----Oprindelig

Re: First PCB pictures of the V2
I have to agree with this, I have a NanoVNA-F and I use it a lot more than the smaller model purely because I can see it. I would be happy to pay extra for a bigger display and as a consequence a

Re: Strange readings on my modded vna.
Can you switch off the calibration and do a full range scan with nothing connected. This will show if there is a hw problem -- NanoVNA Wiki: /g/nanovna-users/wiki/home NanoVNA Files:

Re: problems
Hi Bob, a general point: Some (early?) firmware versions for the NanoVNA "only" allowed operation up to 900 MHz. I suspect you have one of those - and that you will need to upgrade your firmware in

Re: problems
Hi Bob, It is true that when one has several hours, one does not know the exact time. Anyone with multiple VNAs doesn't know which one is accurate - maybe because everything is relative? :-) :-) :-)

Without display user define sweep points useful. Raw data also interesting or/and better calibration model on instrument. Currently no way to define precision oslt model on nanova. Many times coaxial

Re: First PCB pictures of the V2
The firmware can be configured for up to 201 points, but there are still a few minor UI glitches we need to fix before this can be advertised. Sweep rate is by default 100 points/s, and this is what

How many sweep points? and how fast full-range single sweep?

Re: problems
Update.? I recalibrated and now the Smith display is okay.? Maybe I goofed and mixed up the calibration fixtures. Both units have a problem where they turn themselves off without provocation.?

I have two nanoVNAs each with a different problem. One refuses to accept any frequency above 900 MHz. I think I have had that aspect working before but now am not so sure. The other gives me a bad
