SEESII NanoVNA-H Antenna & Vector Network Analyzer 9KHz-1.5GHz with 2.8" EVA Protective Case, Waterproof & Shockproof, Measures S-Parameters, SWR, Phase, Delay, Smith Chart, HW3.7 — Open-Box, 5% Off

Upgraded NanoVNA-H HW3.7: The SeeSii NanoVNA-H Vector Network Analyzer, developed by Hugen, features the latest 3.7 version with a 9KHz-1.5GHz measuring range, a 2.8-inch LCD touchscreen, and a compact, portable design. This antenna analyzer offers excellent vector network measurement capabilities, making it ideal for evaluating antenna resonance and SWR. It's a highly portable, intelligent, and user-friendly tool for electronics engineers, amateur radio operators, or DIY radio enthusiasts

Improved Frequency Algorithm: The enhanced frequency algorithm uses the odd harmonic extension of the si5351, supporting measurements up to 1.5GHz. The metal shield reduces external interference, improving accuracy. The si5351 direct output offers 70dB dynamic range (50K-300MHz), 60dB (300M-900MHz), and 40dB (900M-1.5GHz). The default firmware supports antenna performance measurement

Android and PC Software Control: The NanoVNA analyzer uses NanoVNASaver software, allowing it to connect to the NanoVNA and extract data for display on a computer, which can then be saved as Touchstone files. These Touchstone (snp) files can be exported for use with radio design and simulation software. The VNA supports a USB-C to USB-C connection, making it convenient to connect to Android phones (iPhone not supported)

Abundant Accessories: Come with 1x NanoVNA-H host, 2x 30cm SMA Male to Male RG174 RF Cable, 1x SMA Female to Female Connector, 1x SMA SHORT, OPEN & LOAD simple calibration kit, 1x USB Type-C Data Cable, 1x USB-C to USB-C Line, 1x Lanyard, 1x Touch Plectrum, and 1x custom-designed EVA carrying case. All the accessories are packaged in a sophisticated box. This is a nice VNA analyzer for your own use or as a gift for your friend

Enhanced Protection with Durable Construction：The custom-designed EVA hard shell offers exceptional protection for your NanoVNA-H, safeguarding it from scratches, dust, and accidental damage. Its shockproof, waterproof, and dustproof features ensure your device stays safe in demanding environments, making it perfect for transport and storage

Dual-Layer Storage Organizer: The bag includes mesh pockets and foam dividers, keeping cables, and accessories neatly organized to avoid clutter. The soft lining protects the device from scratches and keeps it clean
