Re: Nano VNA Classic/H upgrade #firmware

 

Hello Andy!
Have You driver for NanoVNA installed?
Driver for H works with H4 too.
Please not use driver from Windows.

I chose the model and the store on Ali based on getting something that would cover the 2.45 GHz ISM band, at a price less than $70 (to avoid paying customs), and generally at minimum price.

Unfortunately, the hardware arrived with almost 0 documentation. The only thing sent was a menu map, which was more or less useless. I was given a link to website, which had some minimal instructions which could not be carried out for calibrating. Corresponding with the vendor was completely unsatisfactory -- I am sure they have no idea what they are selling. For them if they sell a VNA, a pair of sneakers, or sex toys -- its exactly the same thing -- what is the profit margin. (The 35-4400 MHz Spectrum Analyzer came with even less documentation, and I have not yet managed to get it to work).

I had never heard of OwO, Hugens, or any of the dedicated people who developed firmware or software, or help other people on this group, until I came across this group searching for some kind of manual. All power to all of you! And many thanks!

But everyone should be aware that there is a commercial jungle out there. My suspicion is that many more people buy a nanoVNA because they saw a commercial advertisement, e.g. on Amazon or Ali, rather than from reading this group's discourse. Thus appeals in this group to respect the developers' wishes will probably have little effect. My advice to all developers, of whatever, is to first decide what your motivation is. If it is to profit from your work, which is perfectly legitimate, then you should take all of the legal precautions necessary, e.g. patent protection, secrecy, etc. This can be quite costly - probably a minimum of $10,000 for each country over the lifetime of the patent, if you know enough to file yourself (otherwise twice or thrice this figure). And if you need to defend a patent against infringement, the costs can easily get to the M$ range. Know that Murphy's law applies here - if something can be copied, and if it is worthwhile to copy, then it will be copied.

Or, a developer can decide that his or her motivation is not monetary, but rather helping mankind, helping the profession or the hobby, or even obtaining or strengthening one's reputation in the technical community. Then you might tell all and share all, and feel some satisfaction that others are benefitting from your efforts. In my opinion, any middle ground between these two approaches is apt to be frustrating.

How hard is it to simply STOP producing and selling copies of my design? My request is as simple as it gets. Is it that important to Hugen to make a profit off of my work and screw the original developers over while doing it?










Re: Which Type of Jig?

 

I have understood that calibration with a jig in place moves the reference plane of the device to the ¡°business end¡± of the jig, so that it will be accurate despite the stray reactances of the jig. Is this not the case?

In my opinion all of the jigs shown in this thread significantly degrade the true potential of the nanovna. They are fine if you just want to roughly measure reactance across LF through to VHF but they will significantly degrade the performance of the nanovna for critical measurements like component ESR.

Hello jmr,

Roger has shown a very good suggestion for a simple test setup.

It's very easy to criticize something across the board without saying how to make it better.
If you want to make *critical measurements*, like Equivalent Series Resistance, you should buy a device from Keithley.

6ghz unit available?

 

Hello! Just wondering if anyone is offering a unit currently being sold that goes up to 6ghz? I'm on OwO's notification list, but theirs doesn't seem to be in production yet. I'd like to purchase ASAP!
Thanks!

Vladimir,

I got my new H4 in the mail today and seen that the firmware in it was old as well. When I went to upgrade it with the same process I got a new problem with the driver. the USB populated under the Universal Serial Bus Controllers tab and had the below items listed in the picture below.

Is there a different driver process for a new to me H4?

Thanks,

I have tried to show jigs that can be easily built by members of this group. I find them quite accurate for typical measurements by hobbyists and hams. I will post some more test data over the next few days.

I am interested to see what you recommend. Could you please show photos of what you built that can be replicated by group members and used with the standard firmware and apps like NanoVNA Saver and NanoVNA app by OneOf Eleven.

Thanks - Roger

Perhaps, but not at all consequentially at 60MHz and below, IMO.

Which fixture? SMD or Box?

Lead length of test component, cal loads or fixture itself?

These jigs are only used for S11 reflection measurements of components.

For measuring larger components below 60 MHz I use a couple of other jigs
which work quite well. The first one is built with off-the-shelf cables
and a BNC to banana jack adapter. I built a version in a box without the
bulky adapter that works slightly better and is easier to use. The cal
loads were built from double-sided scrap PCB, copper foil and a 49.9 ohm
SMD resistor.
