The PC control software can export (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 is designed to reduce the external interference and improve the measurement accuracy. The 50kHz - 3GHz frequency ranges of the si5351 direct output provides 70dB dynamic. The extended 300M-600MHz band provides 50dB of dynamics, and the 600M-900M band is 40dB of dynamics. Small and portable, easy to use, this project to an RF gadget useful instrument for enthusiast.
