Buying Considerations

Before you buy an automotive lab scope, there are specific considerations you should make. First, you need to have an under of what work you need it for, how you want to use it, and also where you want to use the tool.

After considering these, there are other factors that you should also examine before you make your final decisions. Choosing the right oscilloscope can be challenging.

However, examining these factors will assist you to make the right choice without stress.

Number of Channels:

Different automotive lab scopes have varying numbers of channels. Some have one, two, four, or even ten channels. The number of channels is based on the kind of diagnostic tests that are conducted.

You can use an oscilloscope with one channel to perform a quick assessment or diagnosis, such as detecting the presence of a signal.

Before choosing an oscilloscope, you should deliberate on how many signals you want to be displayed on the screen. Oscilloscopes with two channels are great for reading signals from sensors, crankshafts, camshafts, etc.

Functional Triggering:

You should choose an automotive lab scope that can help to manage visible signals. This is to guarantee accuracy and precision.


The bandwidth of an oscilloscope is simply the maximum signal that it can display or that can go through its front-end amplifiers. Thus, when you want to choose an oscilloscope, buy one with more bandwidth than the highest signal frequency you want to measure.


There are various designs and sizes to select from when it comes to laboratory scopes. There are portable lab scopes and bigger ones that can be linked to a personal computer or a laptop.

Input probes:

Some manufacturers offer input probes and accessories alongside the oscilloscope to expand the input ranges, the areas of applications, and what the device can measure. Extending the input ranges will allow for the measurements of higher voltage and current signals such as injectors, ignitions, etc.

Depth of Memory:

The memory depth of an oscilloscope refers to the size of the memory where it stores recorded data. An oscilloscope with a deeper memory will hold more sample rate for a long time, while an oscilloscope with a smaller memory depth will not capture the waveform correctly.

A large memory depth could also be disadvantageous as it slows down the device.

Ease of use:

Using an oscilloscope that is too complicated to understand can frustrate you and delay your work progress. Thus, choose oscilloscopes that have an easy automatic setup or a memorized setup process.

Some manufacturers can also include user manuals that will help to guide the users through the installation processes.

User Interface:

You should avoid tools built for industrial and scientific purposes as they are complicated and require more time to learn and understand. These industrial tools do not have already set features, and they cannot be used on automobiles without adapters.

As an automobile technician, your oscilloscope should be able to perform certain functions such as adding and editing new inputs, measuring high voltages, sensing temperatures, adding custom waveforms, current clamps, etc.

Sampling rate:

This refers to the frequency at which the laboratory scope samples the tested circuit. Usually, there are two sampling modes used by different oscilloscopes – real-time mode and equivalent-time mode.

You should purchase an oscilloscope with a sampling rate that applies to you. Real-time sampling is usually recommended for automobile diagnosis and 20 million samples per one second is a reasonable sampling rate.


Handheld and portable oscilloscopes are helpful for outdoor purposes. They are easy to set up and can be transported from a place to another.

They can also perform all the functionalities of PC-based oscilloscopes. PC-based oscilloscopes can be used if you do not have to carry them around.

They have wider screens and allows you to store your captured data on HDDs, giving you access to a broader memory depth.


The resolution of an oscilloscope is another crucial factor to consider. It is a term that describes the ability of an oscilloscope to correct small voltages.

This factor is dependent on various factors like the kind of analog to digital converter it has, the input signal preamplifier, etc.
