Yeah, the original Nano (and mini/pocket VNA, plus most old HP gear) are like that. It's possible to remove the drift (and I mean not having to re-calibrate after warmup) with an internal correction

The difference is, that after warmup one gets repeatable results. When I calibrated the cold VNA and started to measure, maybe the very first results showed true numbers, but very soon results drifted

nanoVNA Partner v 0.19 - Max and Min points unit of values displayed fixed; - Main chart size can now be horizontally increased; - Added Q-Factor on the main chart; - Added separate Cal Reset button

Look in the source code of nanoVNA-saver on github Or if you only require perfect calibration standards use this: plusJ=complex(0,1); minJ=complex(0,-1); one=complex(1,0); two=complex(2,0); gm1 = S;

Hello I'm just completing a nice project in Python to Autotune a Magnetic Loop antenna using this great NanoVNA. So far, so good, but now I would like to include a calibration procedure so as to be

In the miniVNA (VNA / J) software there is a thermometer. The green light only occurs above 45 °. I missed this information on nanoVNA.

Please don't keep us in suspense! What are the make and part number for these buttons? Dana

First item, NVIS: Near impossible with a vertical. Not going to happen above about 5mhz under current solar conditions. Suitable antenna would be a dipole for 80/75M low to the ground. Low in this

Gabriel, I think it would be advantageous to at least place the solder pads for an SD TF card slot as I had on my original white Gecko board. Just leave them unpopulated for now and when the firmware

I replaced the jog switch with 3 edge mount through-hole pushbuttons. Any more suggestions (minor changes) before I submit the design for one more round of prototyping? I am not the owner of the

No, UltraVNA should be a full two-port, > 6 GHz analyzer, >120 dB S21 (and S12) at least. I want to build one, if I only had time... Reinier Op 20-12-2019 om 16:32 schreef Larry Rothman:

How about the name: UltraVNA ??
