Intelligent Drawing RBOXII bus analyzer is a compact and convenient device for &Android chipset RFFE bus testing, identify fault points accurately. Compared with the first generation, RBOX II added uart electrical level adjustment function, improved the compatibility. It is also built in with buzzer, enables button feedback and short circuit alarm, more stable. For series, it can fix the problem that the phone has baseband but without serial number. For Android chipset, it focuses on the problems caused by chipset RFFE bus: Remind to Disable Airplane Mode, turn on the antenna, the wireless device is turned off, can't search for the operator and other signal failures. Support offline diagnostics for full series+link with Android models through Intelligent Drawing. The device integrates massive standard RFFE bus data, and the data of popular new models be pushed to the cloud every week. Break through traditional limitation on polarity, accurately capturing abnormal signals in motherboard disconnection/ inveracious soldering. Automatically matching the motherboard bitmap for Android models, accurately locking chip abnormalities. Detect series without connecting with Intelligent Drawing, breaking free from computer and achieve bus data analysis on a single device. Reserved 13mini battery (2406mAh), 12 hours super long endurance. Anti-drop/anti-static/anti-interference, high qualified plastic body, measure data stably.
