?New Upgraded Version: Compared with old version NanoVNA, it save more costs with the addition of ABS casing and the new packaging. Hot stamping technology and plastic inner protection reduce the problems caused by transportation shocks and other processes. Support time domain analysis function (TDR). ?USB-C to USB-C: Support USB-C to USB-C line, more convenient to connect to mobile phones. Compatible with most Android phones with the same screen display (doesnt support for iPhone). Solve the problem of small screen, insufficient brightness and so on. Besides, the battery usage can be displayed on the interface. ?Wide Range Frequency: The improved frequency algorithm can use the odd harmonic extension of si5351 to support the measurement frequency up to 1.5GHz. 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-900MHz band provides better than 60dB of dynamics, and the 900M-1.5GHz band is better than 40dB of dynamics ?Unit is designed to Original Equipment (OE) fit, form and function Simple and practical PC control software, you can export Touchstone (snp) files for various radio design and simulation software through PC software. The TX/RX method can measure the complete S11 and S21 parameters. If you need to obtain S12 and S22, please manually replace the transceiver port wiring. Other details have been improved. ?Requirements accomplished by leveraging Spectra Premiums OE engine management systems design expertise.Platinum connector threads reduce the number of connection points for faster reaction to change. Ceramic-built printed circuit boards are protected by silica gel, providing superior resistance to temperature changes and vehicle vibrations.
