NanoVNA mini analizator antenowy 50 kHz ÷ 900 MHz

Overview:

NanoVNA is a small handheld Vector Network Analyzer (VNA). It is equipped with lcd display, portable device with battery(battery not included). 

This project aim to provide an RF gadget but useful instrument for enthusiast. DIY's vector network analyzer, with reference to the related design of edy555 (https://twitter.com/edy555), modified some circuits, added battery management circuits, and redesigned the PCB. Designed with simple and practical PC control software, you can export Touchstone (snp) files for various radio design and simulation software through PC 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 range of the si5351 direct output provides better than 70dB dynamic. The extended 300M-600MHz band provides better than 60dB of dynamics, and the 600M-900M band is better than 50dB of dynamics. We provide 3 firmware on the network hard drive, you can choose the appropriate brush in accordance with the relevant tutorials, 3 firmware differences are as follows:

nanoVNA_300_ch： 50K-300MHz，5*7 Bitmap font，4 tracks
nanoVNA_900_ch：50K-900MHz，5*7 Bitmap font，4 tracks
nanoVNA_900_aa：50K-900MHz，7*13 Bitmap font，2 tracks (Antenna Analyzer)
