NANOVNA WORLD This page is for information on the nanovna.

Nano means very small. VNA stands for "Vector Network Analyzer. The NanoVNA is tiny measuring device that sweeps from 50 kHz to 900 MHz and has a touch screen. The device uses a rechargeable battery if you need to haul it up to an antenna tower, for example. 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. It also has a touch screen, or 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 reflash 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 300 MHz. There is also provisions for calibrating the device in the field. A Vector Network Analyzer (VNA) is much like a multimeter that measures resistance. But where a multimeter measures a resistor at DC (0 Hz), a VNA measures resistance of an RF or microwave circuit at their operating frequency, measuring both the resistance and the phase (they make up a Vector) of the circuit.
