(Not included in the package).In addition, different from the old version of NanoVNAs, the date and time can be customized, which is convenient for you to further record and save data. The default firmware main function is used for antenna performance measurement
• IMPROVED FREQUENCY ALGORITHM: The Vector Network Analyzer can use the old harmonic extension of si5351 to support the measurement frequency up to 1.5GHz. The 50K-300MHz frequency range of the si5351 direct output provides better than 70dB of dynamics, The extended 300M-900MHz band provides better than 60dB of dynamics, and the 900M-1.5GHz band is better than 40dB of dynamics. Great for troubleshooting antennas and improving performance
• PC CONNECTION & TX/RX FUNCTION: The VNA analyzer uses PC software NanoVNASaver, it can connect to a NanoVNA and extracts the data for display on a computer for saving to Touchstone files. We can export Touchstone (snp) files for various radio design and simulation software through PC software. In addition, the default firmware is mainly used for antenna performance measurement. The TX/RX method can measure the complete S11/S21 parameters (need to manually replace the transceiver port wiring)
• Abundant Accessories: Equipped with 1x NanoVNA-H4(with 1950mA-h battery), 1x USB Type-C cable, 2 x 15cm SMA male to male RG316 RF cable, 1x SMA male calibration kit – OPEN,1x SMA male calibration kit – SHORT,1 x SMA male calibration kit – LOAD,1 x Touchscreen pen.
