NanoVNA-H4 Option

Features:
This Nano VNA is a DIY product that provides perfect vector network measurement capabilities, tiny and handheld, stand-alone with 4-inch LCD display, portable with 1950mAh battery powered or USB powered.
The improved frequency algorithm can use the odd harmonic extension of si5351 to support the measurement frequency up to 1.5GHz. The 50K-300MHz frequency range of the si5351 direct output provides better than 70dB dynamic, The extended 300M-900MHz band provides better than 60dB of dynamics, and the 900M-1.5GHz band is better than 40dB of dynamics.
The default firmware main function is used for antenna performance measurement. The TX/RX method can measure the complete S11 and S21 parameters. If you need to obtain S12 and S22, you need to manually replace the transceiver port wiring
Using PC software NanoVNASaver, it can connect to a NanoVNA and extracts the data for display on a computer, and for saving to Touchstone files. We can export Touchstone (snp) files for various radio design and simulation software through PC software
The metal shield is designed to reduce the external interference and improve the measurement accuracy.
