Best Automotive Oscilloscope Reviews 2020 – Buyer’s Guide

Do you need to view signals in the frequency domain? A digital oscilloscope is probably the best option.

Gone were the days when people were using the old creaky analog oscilloscope,

things have changed now and the newer versions have been upgraded to the best digital oscilloscope.

If you have the automotive oscilloscope, the anticipated resolution is always at your disposal,

whether you are attempting to fix on a weak frequency or plot a course through an electrical distortion.

An automotive oscilloscope is an indispensable device used for troubleshooting communication data stream, actuators, solenoids, sensors, primary and secondary ignitions, among others.

A dedicated automotive oscilloscope can also be referred to as motor-tester, engine analyzer or automotive lab scope.

What is an Automotive Oscilloscope?

An automotive oscilloscope, earlier known and referred to as an oscillograph and unofficially referred to as a CRO, O-scope or scope (for cathode-ray oscilloscope), or DSO (for the more contemporary digital storage oscilloscope), is a kind of electronic test instrument designed to graphically display different types of signal voltages as a two-dimensional plot of one or more signals as a function of time frequently.

Tracing atypical electrical waves on a breaking down equipment will be impossible without an automotive oscilloscope.

Eventually, at some point in your undertaking, you will require only the best oscilloscope in your tool kit,

if you are an electrician or somebody who just prefers tinkering on gadgets.

The question then is; how can you know if an oscilloscope is actually the best in its category?

You will get the answer to this crucial question in the latter part of this automotive oscilloscope review.

Meanwhile, with voltage and time as the Y- and X-axis in that order on a calibrated scale, oscilloscopes show the change of an electrical signal over time.

It is possible for you to adjust the oscilloscope for repetitive signals to be experiential as an incessant shape on the screen.

Oscilloscopes are used in the telecommunications, automotive, engineering, medicine, and sciences industry.

The all-purpose oscilloscopes are used to maintain laboratory work and electronic equipment.

On the other hand, you can use the special-purpose types to exhibit the waveform of the heartbeat or for analyzing an automotive ignition system.

Key Features :

Quite a lot of new users begin by making use of the guided tests to configure all the settings automatically.

Nevertheless, there are many key features to explore when your experience develops. These key features include:

  • The Advanced Digital Triggers: These are distinctive among automotive oscilloscopes. In a situation where there is a very long time gap like when an injector refuses to fire, these trigger modes let you trigger. Moreover, when a sensor signal is out of range, you can set them to trigger and sound an alarm.
  • The Hardware Frequency Measurement: The flow sensors and a number of airflow sensors output a digital frequency signal. As a matter of fact, the majority of the available automotive oscilloscopes cannot extort utilizable diagnostic information from this. However, your PicoScope can change it to a conservative analog waveform.
  • The ECU Filters: A number of signals are quite noisy when wires in the loom get hold of noise from other wires. This feature is used to filter out this noise. The selectable hardware filters of the PicoScope will get rid of this noise, in order for you to perceive what the ECU perceives.
  • The Floating Input Channels: These are exceptional latest technology that allows for safe, reduced-noise measurements even in circumstances where there are none of the inputs grounded. The floating inputs will enable a sole input to carry out voltage drop tests and measurements on non-grounded signals such as hybrid motor drives. The maximum voltage difference allowed between any two-channel grounds is 30 V as far as floating inputs are concerned.
  • The Deep Memory Buffer: Frequently setting up the scope to measure from different components and wait for the fault to happen is the best way to diagnose an intermittent fault. You need an oscilloscope that has a deep memory buffer if you want to capture more than a few injector waveforms, ignition, crank, and minutes of the cam. This will allow you to capture for long periods of time after when you can zoom in without any gaps or loss of detail. The deep memory feature lets you carry out long recordings at high speed. Even in the course of searching for intermittent faults, you capture a comprehensive test drive.
  • The Connect Detect: It is daunting to make sure you have a good connection to the signal you desire to test. But immediately a good connection is detected with Connect Detect feature enabled. In this case, lights on the scope and indicators on screen change from red to green.The on-screen icons fade, as soon as a good connection is established, in order not to obscure the waveform. On the other hand, if there is a change in status when vibration makes a probe lose, the icons will draw your attention to the change.
  • Crisp, Clear High-resolution Display: This is the feature that lets you notice little changes in signal like ignition coil oscillations and a little dip in current when you open an injector. While a deep waveform memory will provide you with a high time resolution, having a high vertical resolution is also essential.
  • Fast Sampling: This is the feature designed for capturing signals faster. Nothing will escape the scrutiny of PicoScope with the sampling rates of about 400 million samples per second.

How to Choose the Quality Automotive Oscilloscope?

The first thing while choosing a digital oscilloscope is not by looking at the adverts or scope specifications rather you need to think where will you use and how will you use it?

  • Determine the purpose of the oscilloscope, where will you use either at the bench, customer site or under the hood of the car
  • How many signals would you require
  • Do you need to view the signals both with frequency domain and time domain or either one of them?

Let’s discuss these points in detail.

Choosing automotive oscilloscope can be a difficult task for a lot of engineers because there are more than a few different models and brands to choose from with widely varying specifications and costs and specifications.

There are quite a lot of features to consider when you are actually shopping for matchless automotive oscilloscopes on the market in order not to make a costly mistake at the end.

Investing some time ruminating about where and what you want to use the automotive oscilloscope for is the first step to selecting an oscilloscope and not just to search for scope specifications or adverts.

Discussed here are some of the factors you need to look for:

1. Ease of Use

In order to make sure the device is easy to use, a number of scopes provide some memorized setup configurations or single-touch automatic setup.

Others have incorporated help system to save you from referring to manual all the time. On the other hand, a number of scopes dispense with devoted user-friendly rotary knobs and substitute them with cheaper buttons for frequently-used adjustments like trigger level, trace position, time-base speed, and vertical sensitivity.

Downloading the manual of the device from the website of the vendor will provide you with the clue about how sensitive it will be to maneuver the oscilloscope as you concentrate on your circuit under test.

An easy to use automotive oscilloscope can save you a lot of frustration in the long run.

2. The Probes and Input Ranges

Consider a manufacturer that provides a whole set of accessories you can use to extend the application device and input ranges when shopping for an automotive oscilloscope.

You need to extend the input range of the oscilloscope with an appropriate input probe if you want to carry out current signals or high voltage measurements like injectors, primary and secondary ignitions among others.

10:1 and 20:1 attenuator, current clamps, capacitive and inductive pick-up clamps, AC coupling adapters and lots more are available.

It is of great importance that the input probes should at least equivalent to, if not surpass, the bandwidth of the scope.

3. The Number of Channels

As a matter of fact, automotive oscilloscopes feature a channel, two channels, four channels and up to ten channels.

When thinking of the one to choose, think about the he number of signals to be displayed.

However, single-channel oscilloscope is enough, if you want to carry out a quick diagnosis to establish the existence of a signal and whether it is in the standard range.

On the other hand, for reading signals from sensors, crankshaft/camshaft correlation, watching thermistor voltage outputs, looking at coil waveforms and injector, as well as looking at throttle position sensor outputs among others, two channels are sufficient.

Automotive oscilloscopes having four separately isolated channels are normally used when dealing with a typical crank no start condition or instantaneous view of the ignition circuit is required.

4. Analogue against Digital Storage Oscilloscopes

Digital Storage Oscilloscopes (DSOs) represent almost all the new oscilloscopes bought nowadays.

In other words, digital storage oscilloscope is the best choice as a lot of users buying oscilloscopes now are changing analogue to digital.

But you have a limited choice if you are tempted to buy the analogue scope.

5. Bandwidth

This is the utmost frequency of the signal that can pass through the front-end amplifiers.

As a result, the analogue bandwidth of your scope must be superior to the highest frequency that you desire to measure.

Only the bandwidth is adequate to make sure a DSO can capture a high-frequency signal accurately.

Make sure you understand the bandwidth specification you want when you are shopping for an automotive oscilloscope.

The bandwidth should always be five times superior on top of the signal’s utmost frequency that necessitates measuring. This should make certain the waveform’s accurate representation.

6. ISO Certified Vendor

Consider buying your automotive oscilloscope from an ISO accredited vendor to guarantee the quality and reliability of the automotive oscilloscope.

ISO/IEC 17025:2005 is fast turning out to be the standard used all over the world by calibration and testing laboratories, according to a foremost test equipment rental organization.

ISO 17025 incorporates an ingredient of suitable skill to the entire concept, despite the fact that there are a lot of resemblances with the former ISO 9001:2008 standard.

For this reason, it is always a smart and good idea to patronize a certified and notable vendor for its quality.

7. PC Interference

Be careful about the interference of your PC. Get ready concerning interference that may occur as a result of power and circuit supply in a situation where a low-level signal analysis is required.

PC components build up electromagnetic noise and they meddle with low-level signals in many cases.

You must keep a process of measurement free of any such interference in order to have a high precision in the course of working with low-level signals.
