Buyer’s Guide – How to Choose an Automotive Oscilloscope


The automotive oscilloscope is an essential tool for solenoids, troubleshooting sensors, secondary ignitions, actuators, and perform other checks when a vehicle breakdown. They are popularly known as engine analyzers, motor tester or automotive lab scope. 

If you wish to pick the best automotive oscilloscope, you must consider this detailed guide into consideration

What is an Automotive Oscilloscope?

An automotive oscilloscope is a sort of electronic test device created to graphically display distinct sorts of signal voltages like a two-dimensional plot of multiple signals as a function of time. This device tests electronic gadgets using electronic signals generated by a device. 

It displays the details from the signal in the form of a graph displaying a relationship between two or multiple variables on two axes, the horizontal and vertical axis. While the vertical axis display voltage, horizontal axis display time. The graph displays various properties like frequency, amplitude, wavelength, and many others.

In addition to electric signals, more other investigations can be made using an oscilloscope. It is useful to study an extensive range of physical processes like vibrations and sound can be converted to voltages or electricity. 

Earlier there were simple, conventionally designed oscilloscopes available. But now technologically advanced, digital oscilloscopes have become a favored choice among the users. From medical, engineering, telecommunications and laboratory science, oscilloscopes are useful in various industries.

Oscilloscope Is Used For?

When assessing the circuits, grounding and power supplies, the signals change too fast to check with a Multimeter. Moreover, there are no breakdown codes saved within ECU but the problem persists because a trouble code is recorded when there is trouble or broken to the negative or power supply, or the actuator or sensor is faulty. But if an actuator or sensor has stopped functioning in the mid-position, it holds no DTC record. 

In such situations, the automotive oscilloscope is an ideal instrument that lets you easily observe output signals from slow-charging analog signals, inductive sensors, charging currents, beginner current waveforms, and more. It visualizes the ignition spark processes to isolate intermittent issues and shows ignition waveforms on a cylinder but shows cylinders simultaneously. 

Should you purchase a scan tool and oscilloscope in a single unit?

It is not a good idea to purchase a scan tool and an oscilloscope in a single unit. The main reason is that both these tools cannot be used simultaneously or at once. Moreover, an oscilloscope is a scan tool meaning that both units share a printed circuit board and the same power supply. Moreover, this kind of oscilloscope does not function as a good automotive unit.

Features Of An Automotive Oscilloscope

User Interface

It is the most important aspect to consider. You must avoid picking a tool originally designed for industrial and scientific applications. These scopes need a lot of time on training and learning. Usually, they don’t have any pre-set functionalities and are not capable of measuring vehicles without adapters.

The user interface of an automotive oscilloscope must be able to edit or add new inputs. It must probe for ignition pick-ups, high voltage measurements, pressure transducers, current clamps, temperature sensors, and more. It is great if it comes with a built-in waveform pattern and allows adding custom waveforms.

You must be able to clearly visualize the ignition spark process and display cylinders next to each other in a parade-style. If it comes with a complete 720 degrees crankshaft rotation measurement ruler, it allows easy observing of all engine cycles.

Sampling Rate

It is the rate of the number of times each second the oscilloscope samples the circuit during a test. Most oscilloscopes hold two distinct sampling modes or rates – Equivalent time sampling and real-time sampling mentioned in Giga or Mega samples per second. 

When choosing an oscilloscope, you must be aware of the kind of sampling the specification applies to. For automotive tracking, real-time sampling is ideal and 20 million samples in a second is an excellent rate.

Bandwidth

It defines the top frequency electrical signals that the scope displays. It displays a correct representation of the waveform, you need to ensure that the bandwidth of oscilloscope is higher than the maximum signal frequency you wish to measure. 

Devices with high-bandwidth can be expensive. Hence, you need to compromise on it. Hence, it is best to pick a tool that offers two times bigger than the maximum measured frequency.

Resolution

It is the oscilloscope ability to rectify small voltages and it relies on numerous parameters like:

  • Input attenuator circuit
  • ADC or Analog to Digital Converter
  • Number of bits of embedded analog to digital converters
  • Kind of input signal preamplifier

Memory Depth

The memory depth is the size of buffer memory where gathered data is stored. A device with an in-depth memory enables users to maintain a high sample rate for a longer time period. A tool with limited memory depth prevents oscilloscope from collecting waveform correctly as the sample points are positioned far apart.

Input Ranges and Probes

Moreover, do look for the manufacturer offering accessories with an oscilloscope to extend the input range and application of the device. The input range of an oscilloscope can be extended to perform existing signal or high voltage measurements like secondary or primary ignition, injectors, and more. 

An oscilloscope may come with different probes like an inductive pick-up clamp, capacitive clamp, and attenuator, AC coupling adapter, current clamp, and more that must either match or exceed your scope’s bandwidth.

Channels

Oscilloscopes may have one channel, four channels, two channels, or up to ten channels. Consider the total number of signals to display while selecting an oscilloscope. A single channel is ideal to perform a fast assessment and identify the presence of a signal.

Double channels are useful for crankshaft or camshaft correlation and reading signals from sensors, coil waveforms, and injectors. 

Automotive with four or more channels are used simultaneously to view the ignition circuit required or dealing with a breakdown in a no-start condition. It also allows looking at the major outputs and inputs together and determines fast the fault.
