Use strong and secure power supply at the same time. The metal shield is designed to reduce the external interference and improve the measurement accuracy.We can export Touchstone (snp) files for various radio design and simulation software through PC software. Using PC software NanoVNASaver, It can connect to a NanoVNA and extracts the data for display on a computer and for saving to Touchstone files.The TX/RX method can measure the complete S11 and S21 parameters (you need to manually replace the transceiver port wiring) This tuner has two huge advantages over the competition: 1) It needs less than 1 watt to complete a. The result is that approximately half of the transmitter power is 'wasted' on a blank carrier and the rest of the power is divided between the two sidebands. It will work with ANY HF radio thanks to the very simple interface, not just with Alinco radios. This Antenna Analyzer is a DIY product that provides perfect vector network measurement capabilities, tiny and handheld.The default firmware main function is used for antenna performance measurement. To produce this AM signal, the transmitter is, in effect, working as three transmitters: one to produce a strong carrier for each of the sidebands, an upper sideband, and a lower sideband.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. The Vector Network Analyzer can use the odd harmonic extension of si5351 to support the measurement frequency up to 1.5GHz.This NanoVNA-H4 with 4inch LCD Touchscreen, Portable with 1950mAh battery rechargeabe powered or USB powered.
