NanoVNA-F V2 Portable Vector Network Analyser 50kHz–3GHz

The Chelegance NanoVNA-F V2 is a portable stand-alone vector network analyser covering 50 kHz to 3 GHz, housed in an aluminium enclosure with a 4.3-inch IPS touchscreen. With a 5000mAh Li-Po battery and low-power design, it delivers up to 7 hours of continuous operation — one of the longest battery lives in its class.

S21 dynamic range exceeds 70dB from 50kHz to 1.5GHz and 60dB from 1.5–3GHz, making it well suited for antenna analysis, filter characterisation, cable testing, and amplifier measurement. Operation via touchscreen or three side buttons, firmware upgrades via USB Type-C, and a USB-A 5V/1A power output add practical versatility in the field.
