The JNCRadio VNA 3G is a portable Vector Network Analyzer with a frequency range of 50 kHz to 3 GHz, offering significant upgrades over its predecessor, the NanoVNA-F V2. Equipped with a more powerful processor and new firmware, it delivers faster, more detailed, and more versatile measurements. The device operates up to four times faster, scanning at 400 points per second, and supports up to 501 measurement points for enhanced detail. It features 13 calibration state storage slots, a built-in real-time clock (RTC) that automatically timestamps saved .snp files, and a robust metal case with a 4.3-inch IPS display. The enhanced processor ensures smoother operation and allows for future firmware upgrades to expand functionality. The JNCRadio VNA 3G supports a wide range of measurements, including S11 and S21 parameters, VSWR, Smith chart, LogMag, phase, delay, Q factor, polar, and linear measurements. It is ideal for analyzing antennas, cables, amplifiers, duplexers, filters, and other RF components, making it an essential tool for radio enthusiasts and professionals seeking portable, high-performance vector network analysis.
