Original NanoVNA Vector Network Analyzer HF VHF UHF Antenna Analyzer Standing Wave Frequency Range 50KHz -900MHz Touch S

Whats the difference between black and white color 1 White is 30cm less than black SMA male to male cable RG174 cable SMA female to female connector2 Black has a shield anti interference white is not available3 White is the carton package black is the plastic case packaging4 Above all this white version is More cost effective than black verison Descriptions 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 transceiver port wiring Features 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 It is mainly for the study of customers who can DIY you need to prepare the SMA cable yourself It has no metal shield The main advantage is that users with strong hands on ability can open the machine to view the circuit structure However when measuring frequencies above 300M it is easy to be interfered by other signals So this product is recommended for learning principles and use at lower frequencies The 50k 300MHz frequency range 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 40
