NanoVNA Vector Network Standing Wave or, Antenna Analyzer 50KHz -900MHz Range

This is a “do it yourself” product and the the small body provides the perfect vector network measuring function. It has a nice 2.8-inch touch screen and a 500mAh battery, which can be used offline for 2 hours. The TX/RX method can measure the complete S11 and S21 parameters. If you need to obtain S12 and S22, you need to manually replace the transceiver port wiring.

Sorry, no manual however, lots of info and suggested uses online and on YouTube.

Some responses from online users….

NanoVNA is tiny but, it sweeps from 50 kHz to 900 MHz and also has a touch screen. The device uses a rechargeable battery if you need to haul it up to an antenna tower, for example. Just as a quick test, you can see early in the video the analysis of a rubber duck antenna. The device shows return loss as a plot and you can use a cursor to precisely measure the values. It also shows a Smith chart of the reactance. If you don’t like the touch screen, you can also control the device via USB. You need software from Google Drive and you can also get the manuals from there. In addition, there are additional firmware files available so you can flash the instrument. For example, you can limit the top frequency to 300 MHz or select a larger font. You might wonder why you’d limit the frequency to 300MHz. According to the manual, the instrument has better performance under 300MHz. There is also provisions for calibrating the device in the field.
