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.

Nano QT software for Nano VNA

John Galbreath 2022/03/14 17:27

VNA-QT is my favorite NanoVNA software for calibration, firmware update, and making charts for presentation.

There is a way to change the minimum, maximum, and number for scale divisions for magnitude.

How do I set these graph scale parameters for SWR (typically ranging from 1.0 to 3.0) and impedance (typically ranging from 10 to 200 ohms) ?

How do I find out which version is installed ?

Following the topic of Nano QT. I like Nano QT. Simple and clean.
Few things are missing or I can not find it yet.
How to Save and Display Saved trace?
In menu S-Parameters there are options: Capture S*1 and Capture S*2. What do they do?
If this is trace being captured where it is and how to display it overlaying with running trace.
