Best automotive oscilloscope is a vital piece of test equipment for electronic engineers working in the automotive industry. It allows the user to view waveforms and see what is going on in a circuit, making it much easier to spot problems that can be hard to troubleshoot with a multimeter. In order to find the best automotive oscilloscope, it is important to look for a few key features.

One of the most important features is bandwidth. This is because many automotive signals are high-frequency and change quickly, meaning that a lower bandwidth will not be able to accurately measure them. Another feature to consider is a good channel count, as this will allow the engineer to measure multiple signals at once. This is especially helpful when checking complex signals and systems, such as those found in the battery management system or powertrain control module. It is also useful to have a feature that decodes automotive buses, as this will make it easier for the engineer to understand the data being transmitted on the bus.

Lastly, it is worth considering the input probe connectivity as this will affect the accuracy and quality of the measurements. There are various types of probes available, including passive, active, and differential probes. Passive probes are the cheapest but do not have a high bandwidth or CMRR, while active and differential probes have higher bandwidth and CMRR but can be more expensive. It is also worth considering the number of automatic measurements and auto cursor tracking functions that are included with the oscilloscope.
