VNA 3G Portable Vector Network Analyser 50kHz–3GHz

The Chelegance VNA 3G is a portable vector network analyser covering 50 kHz to 3 GHz, delivering significant performance upgrades over the NanoVNA-F V2. A more powerful processor and updated firmware enable scan speeds of 400 points per second — four times faster than its predecessor — with support for up to 501 measurement points for enhanced measurement detail.

Housed in a robust aluminium alloy case with a 4.3-inch IPS touchscreen (800×480), it supports S11, S21, VSWR, Smith chart, LogMag, phase, delay, Q factor, polar, and linear measurements. A built-in real-time clock (RTC) automatically timestamps saved .snp files, and 13 calibration state storage slots keep your setups organised. The 5000mAh battery and USB Type-C charging make it a fully self-contained field instrument.
