Designed for automotive design and test engineers, the DSOS054A offers superior signal fidelity to ensure the most accurate representation of your signals. Featuring dual isolated and two differential channels with SafeGround, this scope prevents ground current from entering the instrument and potentially damaging other electronics in the circuit under test. In addition, the DSOS054A has a wide range of inputs, deep memory, advanced triggering, and sophisticated features to make it an essential tool for diagnosing designs and ensuring compliance with regulations.

An automotive oscilloscope is an electronic measuring device used to observe electrical voltage on a screen over time. The X-Y display allows the shape of the voltage to be observed, and the amplitude, phase, and frequency can also be measured. There are many different types of automotive oscilloscopes available, ranging from handheld devices to larger ones that can be connected to a PC for at-home auto diagnostics.

Revolutionizing Vehicle Diagnostics: The Essential Guide to Automotive Oscilloscopes

A key factor to consider when choosing an automotive oscilloscope is the bandwidth. This is important as modern vehicles have many high-frequency, periodic signals such as those found in battery management systems, powertrains, and infotainment systems. A higher bandwidth will allow these faster-changing signals to be accurately captured and displayed on the screen.

Other factors to consider include the amount of channels, a built-in pattern waveform library, and the ability to add custom waves. The motor tester function is another great feature to look for as it can visualize the ignition spark process and help isolate intermittent issues. It can also display all the cylinders in a “parade” style and can measure engine speed over 720 degrees of crankshaft rotation.
