When we talk about the oscilloscope, the image that comes right away is that of this great device that sat majestically on a table in the class of physics, electronics, and technology. This is the device that was used to view the signal delivered by the dynamo of a bike.
Today, it is practically obsolete and hardly exists anymore. Meanwhile, the digital oscilloscope appeared and stole the show. The latter is also gradually catching up with PCs that can transform into an oscilloscope. Just know how to do it.
What do you need?
Transforming a PC into an oscilloscope requires you to collect hardware. You will naturally need a functional PC for reading signals and a suitable cable for capturing them.
Regarding the PC, it is enough that it is functional and that its sound card is in good condition. Indeed, it is the sound card that we will use to transfer the signals on the PC.
As for the cable, we will make one, with two different plugs depending on both sides of the cable. One side will be equipped with a headphone jack. This is the one that will be connected to the sound card of the PC. The other hand will be provided with two crocodile plugs that we will connect to the system we want to measure.
Also, you will need some software on your PC to translate the received signals into an image since your PC does not have these capabilities intrinsically. Several software packages are available for download, and each plays a well-defined role in a PC transformed into an oscilloscope.
The manufacture of the cable that we will use to turn your PC into an oscilloscope will ask you to highlight your talents as a handyman. Indeed, it will be necessary to heat the soldering iron to join the plug of sound at the first end and the cards crocodiles on the second.
In case you can not do it, you can choose a more straightforward solution, which is to look for this type of plug in the trade. This is not very common, but you can find it more easily on the internet at a lower cost. This type of purchase is more plausible on online sales sites.
Once you have your cable, you plug the sound plug into the microphone output of your computer and the alligator cards on the terminals of the device you want to measure the voltages.
Now the software starts to signal the presence of electrical signals. Depending on your information needs, you can adjust the settings from the commands offered by the software you use.
