Application of automotive oscilloscope

　　The automotive oscilloscope is an effective tool for quickly judging the faults of electronic control systems. It is simple to use, easy to master, and has accurate waveform display. In actual operation, just like clicking on a menu, you only need to select the content to be tested, and you can directly observe the waveform of the electronic components without any settings or adjustments. The waveform display of the oscilloscope uses a graph of voltage changes over time to reflect an electrical signal. It can judge the working condition of the working parts very intuitively and accurately, providing convenience for troubleshooting.

　　In the electronic control system, the signal change rate of some electronic components is fast, with a change cycle of one thousandth of a second. There are also many fault signals that occur intermittently, sometimes not, sometimes not. This requires the scanning speed of the test equipment to be much higher than the fault signal speed. The automotive oscilloscope can quickly capture electrical signals and display these waveforms at a slower speed so that maintenance personnel can observe and analyze them at the same time. It can also record signal waveforms in a storage manner and repeatedly observe fast signals that have occurred, providing a quick way to analyze faults. In the electronic control system, whether it is a high-speed signal or a slow signal, an oscilloscope can be used to observe the working condition of the tested component, and the waveform can be observed to know whether the fault has been eliminated.

　　By using an automotive oscilloscope to test the signal waveform and signal voltage changes of the sensor output, the performance of the sensor itself can be determined, and thus the operation of a system can be determined. For example, for a car equipped with an oxygen sensor feedback system, using an oscilloscope to test the oxygen sensor signal can give a good understanding of the operation of the entire feedback system, providing convenient conditions for capturing fault information.
