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.\u003cbr\u003e\nThe 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\u003cbr\u003e\nUsing PC software NanoVNASaver, it can connect to a NanoVNA and extracts the data for display on a computer, and for saving to Touchstone files.
