An oscilloscope is an instrument that graphically displays electrical signals and shows how those signals change over time. Engineers use oscilloscopes to measure electrical phenomena and quickly test, verify, and debug their circuit designs. The primary function of an oscilloscope is to measure voltage waves.25 Mar 2021
What is a scope on a car?
The automotive scope is in some sense a standard oscilloscope but has an added functionality designed for the testing and troubleshooting of cars. It is a diagnostic tool which graphically displays key features of a car.
What can an oscilloscope measure?
An oscilloscope measures voltage waves. Remember as mentioned earlier, that physical phenomena such as vibrations or temperature or electrical phenomena such as current or power can be converted to a voltage by a sensor. One cycle of a wave is the portion of the wave that repeats.
How many MHz oscilloscope do I need?
Determine what you need use the 'five times rule' For example, a 100 MHz oscilloscope is usually guaranteed to have less than 30% attenuation at 100 MHz. To ensure better than 2% amplitude accuracy, inputs should be lower than 20 MHz. For digital signals, measuring rise and fall time is key.19 Mar 2019
What is an oscilloscope used for in automotive?
An automotive oscilloscope works to display different signal voltages on a graph. When electrical parts or systems in a vehicle are tested, electronic signals are generated. An oscilloscope is going to capture these electrical signals in graphs to allow users to measure and see what is going on in a specific system.25 Jan 2021
How do I choose an oscilloscope?
Select an oscilloscope that has sufficient bandwidth to accurately capture the highest frequency of your signals. Remember 'the five times rule'- select an oscilloscope which, along with the probe, offers at least 5 times the maximum signal bandwidth for better measurements with fewer errors.21 Aug 2020
