NanoVNA-F V2 SDRGEEK Vector Analyzer 4.3inch Screen 50k to 3GHz Range

Description

Product Overview

The NanoVNA-F V2 from SDRGEEK is a handheld vector network analyzer that combines a large 4.3‑inch IPS TFT LCD display with a wide measurement bandwidth of 50 kHz to 3 GHz. The device supports full S‑parameter analysis, SWR, phase mapping, group delay, and Smith chart visualization, making it a versatile tool for antenna tuning, filter testing, and RF component characterization. Its compact dimensions of 9.88 × 7.36 × 1.85 inches and lightweight aluminum alloy chassis (15.87 oz) provide portability without sacrificing durability. Powered by a built‑in 5000 mAh lithium‑ion battery, the NanoVNA‑F V2 offers up to seven hours of continuous operation, and the battery can double as a power bank for external devices. Included accessories comprise two 200 mm SMA‑JJ RG405 cables, a full SMA calibration kit (Open, Short, 50 Ω Load), and a variety of SMA adapters, ensuring you have everything needed for immediate field deployment.

Usage

The NanoVNA‑F V2 is designed for both professional engineers and hobbyist enthusiasts. Its intuitive touchscreen interface allows quick setup in outdoor antenna farms, indoor lab environments, or on‑the‑go field service. The large high‑resolution screen makes complex data such as Smith charts and phase plots easy to read even in bright sunlight. Users can perform real‑time impedance matching for HF, VHF, UHF, and microwave bands, troubleshoot Wi‑Fi routers, evaluate PCB traces, or verify the performance of custom filters. The robust aluminum case shields the internal circuitry from electromagnetic interference, ensuring accurate measurements in noisy environments. The device’s USB‑C port enables firmware updates, data export, and connection to a laptop for advanced analysis using open‑source software.
