For experienced oscilloscope users, the 4823 may be a suitable choice for training, vehicle design or complex diagnostics. This oscilloscope (like our earlier generation 4423 and 3423) has a common ground reference rather than floating inputs but does have additional protection against inadvertent connection of ground to power. The input voltage range is only 50V so attenuators are required when measuring signals from inductive components such as injectors The 4823 allows you to simultaneously monitor more channels for those applications with more complex signal interactions and also includes the same low-voltage signal generator as the PicoScope 4824.
