Automotive Oscilloscopes

What is the best automotive oscilloscope?

This doubt is very common for those who work in the automotive area because of experience in the main automotive workshops have recommended using the four-channel oscilloscope or more. Since with more available channels they are much more exact.

Best Automotive Oscilloscope Brands

• Signstek
• Maxiscope
• Hantek
• Owon
• PicoScope

Types of Automotive Oscilloscope

Analogs: The latter work directly with an applied signal, and this, amplified, deflects a beam of electrons vertically, proportional to its value. In a cathode ray tube comes the electron beam generated by the cathode and accelerated by the anode.

Digital: digital oscilloscopes are the ones that are currently replacing analogue ones, thanks to their quick sampling, more accurate results automatically, advanced calculations, and can also be used to measure voltage signals.

These types of oscilloscopes have advantages and disadvantages, for example, the analog is preferably favorable when you want to observe in real time the rapid changes of the input signal, while the digital is ideal if you want to analyze non-periodic events such as peaks of tension that originate at random.

Parts of an oscilloscope

Either of the two types of oscilloscope, its parts are as follows:

• Amplifier for vertical signal
• Amplifier for horizontal signal
• Power supply
• Time base
• Synchronism system.

Spectrum analyzer

It is an apparatus that is used to visualize the frequency and dimension of an electromagnetic wave through a screen where it details the spectral elements in a frequency span, whatever the type of wave, among them: acoustic, optical and electrical.

On the other hand, a spectrum analysis is the process by which the different intensities of a specific frequency are studied more precisely and in detail, that is, it studies each part in a profound way and that any wave is impossible at first sight.

How to connect an automotive oscilloscope?

• Before turning it on, you must ensure that the intensity control is low.
• Now, turn it on
• Wait for the tube to warm up to start working
• Increase the intensity control until a not very bright horizontal line appears
• Adjust the focus control until a very thin line appears
• Connect the probe to the input of channel one (CH1)
• Plug the probe tip into the outlet (CAL)
• Configure the time scale and amplitude controls for CH1 until a square probe appears that occupies most of the screen, and at least one full cycle is visible.
• Disconnect the probe tip from the square wave output
• After doing these procedures, the oscilloscope is now ready to be used.

Automotive oscilloscope for laptop

They are more comfortable, lighter and you can connect them to the USB port of your computer and with a previously installed software, it can work perfectly in the same way as large oscilloscopes.

Automotive oscilloscope course

Currently you can search online or specialized academies for automotive oscilloscope courses you can also search for the areas where you live the different schools or academies that teach basic electronics courses that teach readings with oscilloscopes.
Below we describe the two best brands of automotive scanner in the market.

Hantek brand automotive oscilloscope

It should be noted that this is one of the most recognized brands for the use of oscilloscopes, this type of device is available in several models, including:

• Process calibrator HT824
• iDSO 1070 Series
• Hantek 6000BC
• HSA 2030 Series
• PS O 2020
• DSO 8000 E series
• MSO 7000 B
• HDG 2000 B

OTC Automotive Oscilloscope

This type of oscilloscope has the ability to be able to differentiate two signals at the same time thanks to its two channels of great accuracy, being this type one of the best and newest existing in the automotive market, one of its particulars is that it works with a frequency 25 MHz

Additionally, the OTC oscilloscope, brings an option called Perception OTC or what is the same fault capture with its own button, is an intelligent application that is used to detect a normal and an unusual signal, records these moments and performs an accurate analysis to be able to solve the problem detected.

Components of the OTC Automotive Oscilloscope

• 2 channels available with their respective cables.
• Graphic multimeter
• Database for vehicles of specific brands
• Web updates
• 110 volt adapter
• Probes
• Second ignition clamp
