Hi Jean - Rune Broberg is the author of nanovna saver, which I think uses a minimal subset of nanoVNA commands that work with most firmware, particularly including originally installed by Hugen, which

Hello, we have, with this fantastic device and everyone's contribution, a great tool for our hobby. We see quite often a new firmware popping up. Is there a way to understand how a new firmware will

It doesn't look like hugen has any plans to update his original NanoVNA-Sharp application. Both QRP and neb40gsm@... have done an excellent job of taking hugen's reverse engineered NanoVNA-Sharp

Certainly, that can be noted in the Smith plot. Agreed; in this case one is a legit cal standard and the other is about 47.5 Ohms and 1.4nH

The T connector is not accounted for by the calibration..... BNC 50 ohm terminators can be very poor. They are sometimes a 1/8 watt axial lead resistor in the metal extension of the BNC. R varies

Hi Wolfgang, i'm glad you like it, the design and solution is Neb's merit - i just tested it and gave an opinion. I like it too, with clever solutions. 73, Gyula

cal adapters appear to be collectors item

BNC Tee with terminators at the end of a pigtail is far from ideal... I suppose that mixer distortion may be inconsistent among samples. FWIW, when calibrated for smaller ranges, e.g. 200-800MHz my

HiGyula, a very nice and useful program! I hope it will be freeware and open source. It was a good idea to find the minimum SWR automatically. As an example I tested a DiskCone antenna for receiving

Is if fair to conclude that for your HW there is no difference between 8 mA drive (power 3) and 6 mA drive (power 2)? Strange, I did clearly see a difference on my HW -- NanoVNA Wiki:

The rise approaching 900MHz is related to power 2, not just random noise, switching power back and forth with saved calibrations. I suppose there is noise in calibration ( does it employ averaging? )

Here ya go..... https://www.amazon.ca/Mustwell-NanoVNA-Network-Analyzer-Standing/dp/B07XMDVYGN/ref=sr_1_158? $628 CAD for 1 nanoVNA on Amazon.ca - comes with 'free' shipping too ! Only a few

First capture is with 50 Ohm calibration at power 2; second is then with 50+50 tee and 2dB/div:

Only a few individuals here have experience with more than one nanoVNA, with most acquired from vendors who may ship different versions at different times. According to @gabuchan, there are 3 main

Oristo, Can you do a calibration and a measurement of a 25 ohm resistor after you have fixed the output power to 6mA, so in console mode power 2 and then the calibration and measurement and see if

Hi neb, The program has been tried by others and works well with Windows XP. Thanks to neb for writing the program.

Ordered this one today..tnx for the recommendation. There are so many out there it is hard to make a decision. Your advice is based on something other than " a good deal". Now I need to learn how to

I always want at least 5 calibrations and do not recall using more than 3 traces at a time.

SCANRAW is for applications to grab e.g. more than 101 points, optionally with averaging, while paused.
