Portable Handheld Vector Network Analyzer 50KHz-900MHz Digital Display Touching Screen Shortwave MF HF VHF UHF Antenna Analyzer Standing Waves This is a DIY product with vector network measurement function. It includes a 2.8-inch touching screen, TX/RX measurement, can determine the complete S11 and S21 parameters, if you need to get S12 and S22, you need to manually replace the trans-ceiver port wiring. Features: The PC control software can export Touchstone (snp) files, which can be used for various radio design and simulation software. The improved frequency algorithm can use the odd harmonic extension of si5351 to support the measurement frequency up to 900MHz. The metal shield is designed to reduce the external interference and improve the measurement accuracy. The 50k-300MHz frequency ranges of the si5351 direct output provides better than 70dB dynamic. The extended 300M-600MHz band provides better than 50dB of dynamics, and the 600M-900M band is better than 40dB of dynamics. Small and portable, easy to use, this project aims to provide an RF gadget but useful instrument for enthusiast.
