SainSonic RA-60C shortwave antenna icon vector impedance analyzer is based on a 50-ohm measuring shortwave antenna system experimental apparatus. Can accurately measure the reactance X, standing wave SWR, resistance R, and the complex impedance Z parameters. To check and adjust the antenna resonance short, bandwidth matching. The antenna analyzer requires users to have a certain radio basic theoretical knowledge and an understanding of the performance of the device; proper operation and in order to better use it. The device acts as a DIY work, compared with the commercial machine shell appearance may have regrets. But this regret should not be significant. The device has a higher resolution than the commodity machines and precision, test speed, a more friendly user interface, more focus on user experience, portable small size, high quality power management to get more use of time and so on. Specifications: * Display: Sharp Transflective TFT, 1600 million colors * VSWR 1.00 - 99.99, million level below market instruments * Frequency range :0.5-60MHz * Frequency stability: Basic Operations:
