QBG-3E Full digital display high-frequency Q tableDetailed product description：

The QBG-3E all digital display high-frequency Q meter inherits the digitalization and humanized design of high-frequency Q meters (QBG-3D and AS2853 high-frequency Q meters) over the years. It adopts three innovative technologies: digital main capacitor, LCD large screen liquid crystal display full parameters, and DDS direct digital synthesis, which greatly improves the technical performance and functionality of high-frequency Q meters. It completely changes the outdated situation of the old Q meter relying on two sets of auxiliary tables printed on the panel to calculate L, C, and Q. The QBG-3E high-frequency Q meter has clear reading, no need for conversion, easy operation, and is particularly suitable for quality analysis, quality control, scientific research and production of electronic components. It can also be used as a scientific research experimental instrument in electronic information, electronic communication, materials science and other majors in universities
