SEESII NanoVNA-H handheld vector network analyzer, 10 kHz–1.5 GHz. Measure S11/S21, VSWR/SWR, Smith chart; USB-C PC/Android control, SMA cal kit, ESD protection.
You want to tune antennas, verify filters, and see matches without hauling bench gear. NanoVNA-H (HW3.6) gives you lab-style visibility in a pocketable vector network analyzer. Power it on, run a quick open/short/load calibration, and you’re looking at S11/S21, VSWR/SWR, phase, delay, and a live Smith chart from 10 kHz to 1.5 GHz—perfect for MF/HF/VHF/UHF work.
Prefer a bigger screen or automated sweeps? Plug in via USB-C and use your favorite PC/Android app to capture traces and export Touchstone (SNP/S1P/S2P) files for simulation. The redesigned board adds battery management, metal shielding, and ESD protection, so field measurements are steadier and safer. In short: you get reliable results, faster setup, and fewer trips back to the bench.
- 10 kHz–1.5 GHz coverage – Tune and validate antennas, filters, and matching networks across MF/HF/VHF/UHF.
- S-parameters with insight – Measure S11/S21, view VSWR/SWR, phase, delay, and Smith chart for real matching work.
- Handheld & portable – 2.8" 320×240 color touchscreen with clear traces; runs stand-alone or over USB-C.
- PC/Android control – USB-C CDC serial interface for TinyVNA/NanoVNA apps; capture data, automate sweeps, and manage settings.
- Touchstone export – Save SNP files to the included micro-SD for RF design and simulation workflows.
- Improved hardware – Metal shielding and ESD protection enhance stability and accuracy in noisy environments.
- Practical dynamics – Typical dynamic range ~70 dB (50 kHz–300 MHz), 60 dB (300–900 MHz), 40 dB (900 MHz–1.5 GHz).
- Simple field kit – SMA cal kit, SMA-M/M leads, and F/F adapter cover common setups in minutes.
- Battery management – Built-in rechargeable battery with USB-C charging; use a power bank for extended sessions.
