{{EN_1} table of Q type (QBG-3 improved version)Detailed product description：

WY2851 Q-meter (QBG-3 improved version) is a universal, multi-purpose, and multi range high-frequency impedance measuring instrument. This machine is a replacement product for the old QBG-3 high-frequency Q-meter. By using a stable amplitude digital signal source and a broadband low impedance injection transformer, the tuning indication is stable and the frequency response error is small. Reasonable testing circuit design to reduce residual values. By adopting technologies such as automatic positioning and Q-value pre setting, as well as adding fast tuning and comfortable hand feel, the sorting and testing speed of the production line has been greatly increased. This instrument has a novel appearance, small size (about half of QBG-3), and light weight.
