Autel’s MaxiSYS lineup has long set the industry benchmark for professional automotive diagnostic technology, with an extensive range of best-selling models designed for workshops, master technicians, and automotive service professionals across the globe. One of the most frequent questions we get from customers during the buying process is: which Autel diagnostic tablets include built-in oscilloscope functionality, and which model is the best match for my workshop’s needs? Oscilloscope capabilities are indispensable for advanced waveform analysis, precise electrical fault isolation, and in-depth vehicle system diagnostics, making it critical to select the right tool to boost your repair efficiency and accuracy. In this guide, we’ll walk you through a comprehensive comparison of Autel’s oscilloscope-enabled diagnostic scanners, including the MS919, Ultra (EV), MS909S2, MS919S2, and Ultra S2.
To start with a quick rule of thumb: all Autel MaxiSYS models equipped with a VCMI or VCMI2 communication module support oscilloscope functionality. Historically, this capability was limited to flagship models like the MS919, Ultra, and Ultra EV, all of which come with integrated oscilloscope features out of the box. More recently, Autel has launched the next-generation S2 series, which takes oscilloscope diagnostics to new heights with enhanced capabilities, more intuitive signal analysis, and improved user-friendliness. All oscilloscope-enabled models can also be paired with the Autel MaxiSys MSOAK Oscilloscope Accessory Kit, allowing technicians to unlock the full potential of their tool’s oscilloscope for advanced diagnostic work.
