4 Inch 50kHz-6.3GHz / 10KHz -1.5GHz Vector Network Analyzer Antenna Analyzer HF VHF UHF SWR HW Version 4.3(4Inch NanoVNA-H4)

- This is a DIY product that provides 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 , 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.
