All About Automotive Oscilloscope

The oscilloscope, which is a measuring device that allows us to see the changes in electrical voltage over time, is also frequently used in the automotive field. What is an automotive oscilloscope? How to use the automotive oscilloscope? How to read and interpret automotive oscilloscope patterns? How to get an automotive oscilloscope? Let's examine together. 

What is Automotive Oscilloscope? 


The automotive oscilloscope is in a sense a standard oscilloscope, but it has an additional function designed to test and troubleshoot cars. It is a diagnostic tool that graphically displays the basic features of a car. Automotive oscilloscope is an indispensable device for almost all automobile maintenance. Cars are getting more and more complex with an increasing number of electronic and electrical components each year. Standard measurement tools will no longer be sufficient for troubleshooting and the automotive oscilloscope will come into play. The automotive oscilloscope is a device that can be used not only for the newest cars, but also for older cars. 

The automotive oscilloscope is optimized for the automotive industry and offers specially designed features compared to ordinary oscilloscopes. The automotive oscilloscope has special software that helps it run certain car system tests. For example, it can measure the pressure in multiple cylinders at the same time. The possibilities of the automotive oscilloscope are quite wide. These possibilities increase with each new software update. Some key features are: testing charging circuits, starting process, ignition process, testing different sensors, performing actuator tests, pressure tests, and testing CAN and LIN Bus communication. To make use of all these advantages, it is necessary to know how the automotive oscilloscope patterns are used. 

How to Use an Automotive Oscilloscope 


The oscilloscope is an important element of the electronic world from past to present. Especially in the past to repair any cars, it was necessary to deal with many cables, to determine damage and then to carry out repair work in the area identified. However, with the development of the automotive oscilloscope patterns within the technological possibilities, this process became much easier. While the first use of the oscilloscope in the automotive industry is made with large machines, it has become much easier today. Damage can be detected thanks to a laptop and a portable automotive oscilloscope. And instead of spending thousands of dollars to do this, you can buy automotive oscilloscope at a much more affordable cost. You can see the signals on the computer screen by connecting the cable to the computer and the car. Detecting using the automotive oscilloscope is actually quite simple.

How to Read and Interpret Automotive Oscilloscope Patterns 


In order to read and interpret automotive oscilloscope models, important technical features must be known. These features of the automotive oscilloscope are as follows. 

Bandwidth: Bandwidth is a feature that defines the highest frequency electrical signal that the oscilloscope can display. To ensure an accurate representation of the waveform, you must make sure that the oscilloscope bandwidth is higher than the maximum frequency of the signal you need to measure. However, it should be remembered that unnecessary high bandwidth may result in noise or unwanted signals on the oscilloscope screen. 

Sampling Rate: The sampling rate shows how many times the oscilloscope sampled the circuit under test. Most oscilloscopes have two different sampling rates or modes. It is real time sampling and equivalent time sampling specified in mega or giga samples per second. When choosing an oscilloscope, make sure you know the sampling type to which the specification applies. 

Memory Depth: The size of the buffer memory where the captured data is stored on the oscilloscope is known as the memory depth. A deep memory oscilloscope allows users to maintain a higher sampling rate for a longer period of time. This is most noticeable when zooming into a signal. A limited memory depth will prevent the oscilloscope from capturing the waveform correctly because the sample points are located too far apart. 

How to Buy an Automotive Oscilloscope 


It may make more sense to avoid oscilloscopes originally designed for scientific and industrial applications. These oscilloscopes are harder to use and take too much time to learn. There are some points to consider when buying automotive oscilloscope. Are automotive presets included in the database? Is the oscilloscope capable of adding and editing new presets? 

The user interface can be used by the user for high voltage measurements, ignition receivers, current clamps, pressure transducers, temperature sensors, etc. Can add or edit new existing input probes for? Is there a built-in pattern waveform library and is it possible to add new custom waveforms? As a result of all these questions, you can easily buy automotive oscilloscope.
