How To Choose the Quality Automotive Oscilloscope?

The first thing while choosing the best automotive oscilloscope for you, 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?

Choosing automotive oscilloscopes 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 advanced digital automotive oscilloscopes on the market in order not to make a costly mistake at the end.

There are very high demands from technicians on digital automotive oscilloscopes, unlike the old analog ones which are now old fashioned and aren’t quite used by professionals.  

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:

Ease of Use

In order to make sure that your handheld device is easy to use, numerous scopes provide some memorized setup configurations or a 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 user 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.

The Probes and Input Ranges

Consider a manufacturer that provides a whole set of accessories you can use to extend the application device input range and when shopping for a handheld 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.

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.

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 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.

Analogue against Digital Storage Oscilloscope

Digital Storage Oscilloscope (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.

Bandwidth

The bandwidth parameter specifies the maximum frequency electrical signal that the oscilloscope can display.

To guarantee an accurate depiction of the waveform, the oscilloscope bandwidth must be greater than the maximum frequency of the signal to be measured.

 However, excessively high bandwidth will result in noise or undesired signals appearing on the oscilloscope screen. It is preferable if the scope bandwidth is appropriate for the measuring task.

The frequency at which the input signal is reduced by 3dB is referred to as the bandwidth. This implies that signals recorded near the oscilloscope’s bandwidth cannot be correctly captured. 

As a result, the oscilloscope bandwidth must be approximately twice as big as the maximum recorded frequency.

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

As a result, the analogue bandwidth of your oscilloscope 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 definition and 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.

Sampling rate

The sample rate of an oscilloscope is the number of times per second that it samples the circuit under test. 

An oscilloscope’s sample rate is comparable to a movie camera’s frame rate. It influences how much waveform detail the scope is capable of capturing.

Most oscilloscopes have two sampling rate speeds or modes: real-time sampling rate and equivalent-time sampling rate (repetitive), both of which are expressed in mega or giga samples per second (MS/s or GS/s).

When selecting an oscilloscope, make sure you understand what sort of sampling is covered by the specification. 

Equivalent-time sampling is not suggested for automotive usage since it is only appropriate for periodic signals and hence unsuitable.

You will not be able to determine the real amplitude and length of any particular pulse if the sampling rate is inadequate.

For virtually all diagnostic applications, a sample rate of about 20 million samples per second would be a reasonable choice.

For automobile diagnostic purposes, a decent oscilloscope will take around 20 million samples per second, however the precise number of samples may vary from unit to unit.

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.

Memory depth

The memory depth refers to the size of the buffer memory in which the collected data in the oscilloscope is kept.

A deep memory oscilloscope allows users to maintain a greater sample rate for a longer length of time. This is especially noticeable when zooming in on a signal.

Because the sample points are too widely apart, 

an oscilloscope with a restricted memory depth will be unable to capture the waveform properly.

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.

Choose Functional Triggering

Opt for an automotive oscilloscope with functional triggering because it aids in managing the signal display that can be viewed by the bare eye, to make it snugger and more precise for viewing.

While shopping for a certain oscilloscope, it is imperative to select the one that offers incredible visibility and wider boundary to ensure a better triggering response.

Frequently Asked Questions
