Beware of cheap underperforming clones

As of 2022 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.

See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

Control NanoVNA from python script


reuterr 2020/06/23 10:08

Hello,

Is there a plan to adopt Hugens "Control NanoVNA from python scriot" also to the V2 version?
It will be very useful to capture the display memory for a screen shot.
For the Python program see in the appendix.

[ Rudy, there is a V2 python script located at https://github.com/nanovna/NanoVNA-V2-firmware/tree/master/python . Because the V2 does not support all the NanoVNA console commands, some functions are not supported.]

It will be very useful to capture the display memory for a screen shot.

['capture' is one of the console commands not supported by the V2 so screenshots are not supported. The native VNA-QT application does not support screenshots so its probable capturing is not currently supported in firmware.]

The NanoVNA made remote operation a piece of cake for beginners. Because the V2 does not support control from a serial console and the display blanks out to "USB Mode" when talking to it, you need more advanced programming to control it.

As a matter of usage, I only run the v2 using nanovna-saver from a computer. This gives me lots of high resolution plots that I can screen-capture or save an S1P or S2P file. So, here's a screen-shot I've got lying around, and a screen-shot of an excel comparison of a bunch of data... At my age the 'look at screen' thing doesn't work very well for the tiny screen and even changing sweep range is an agony, so... that's me.
