Vector Network Analyzer HF VHF UHF UV 50KHz-900MHz 2.8Inches Portative Analyzer for Analyzing Network Phone.
The improved frequency algorithm can use the odd harmonic extension of si5351 to support the measurement frequency up to 900MHz.
Small and portable, easy to use, this project aims to provide an RF gadget but useful instrument for enthusiast.
The extended 300M-600MHz band provides better than 50dB of dynamics, and the 600M-900M band is better than 40dB of dynamics.
The metal shield is designed to reduce the external interference and improve the measurement accuracy.
