Re: Measuring crystal parameters with classic NanoVNA?
Which variant (if any) works with the Classic (Pre-H) VNA. This never seems completely clear from the descriptions - I think because there's no consistent way to describe the original unit. thanks, M

I have gotten some great input about this, but it remains a problem that such outputs as ¡°real¡± and ¡°imaginary¡± come with no documentation as to what they are. I have written a 1 pager that

I think you will find this video by W2AEW on measuring crystals with a NanoVNA interesting. His videos are technically accurate, easy to follow and quite informative. He uses an earlier version of

Re: Saving
Joe, I suggest you read the Absolute Beginners Guide to the NanoVNA. Your question and many others that new users ask are described in detail. It is in the files section of this group.

Re: Saving
Same answer to both questions: yes, saving in 0, 1, 2, 3, or 4 lets you open that calibration any time using the RECALL command. And if you set up all the traces you want during a calibration, and

Re: Saving
Joe, The prior save-1 action will keep 1 as you set it up. That is all cals, freq range, display etc... But, if you decide that you do not like some item in 1... as long as you do not significantly

Re: Saving
Ok, Good, Now if I was to save to Save-1, how does one use save 1 in the future? Joe WB9SBD

Re: Saving
Save to location zero everything like cal and displays will boot to all saved items. You can do the same with all other locations. But, requires a recall after turned on.

Re: Saving
Hi Joe , you have to save 0 . When you turn on the nanovna , by default the register number 0 is recalled. Maurizio Iz1MDJ

I recently joined the club and bought a NanoVNA, which I think is a "classic" version clone (no case, no shielding). It is currently running NanoVNA-H firmware 0.4.5-1-efbbceca. My current goal is to

Re: Measuring Inductance.
Interesting how a little DX35 with its small output tube would provide a similar set of L taps for the pi net as a pair of big bottle 3-500 Z's. Apparently the ratio of plate V to plate I and the fact

Re: Measuring Inductance.
I took my old DX35 tank coil that has multiple taps and my Mosley traps and they pretty match your Now is values. Here is your now is: 10 = 1.1uH 15 = 1.8uH 20= 2.94uH 40= 6.46uH 80= 12.46uH Ps I used

Re: Measuring Inductance.
You have to change the stimulus range I ended up for my coils 1-8 mhz then 10- 30 mhz an then a narrow span. Also I didn't recalibrate just to see what would happen. Down in the HF region results were
