How to Use a USB Oscilloscope Software for Free
A USB oscilloscope is a device that allows you to measure and analyze electrical signals using your computer. It can be useful for hobbyists, students, engineers, and anyone who wants to learn more about electronics. However, a USB oscilloscope can be expensive and not everyone can afford one. Fortunately, there is a way to use a USB oscilloscope software for free and get similar results.
How to Use a USB Oscilloscope Software for Free
In this article, we will show you how to use a free software called Zelscope that can turn your computer into a virtual oscilloscope. Zelscope can work with any sound card or external audio device that can capture audio signals. You will also need a simple probe that you can make yourself or buy online. With these tools, you will be able to perform basic measurements and experiments with your USB oscilloscope software for free.
What You Will Need
To use Zelscope as a USB oscilloscope software for free, you will need the following:
A computer with Windows XP or later.
A sound card or an external audio device that can capture audio signals.
A probe that can connect to the audio input of your sound card or audio device. You can make one yourself using a 3.5 mm jack, a resistor, and two alligator clips. Alternatively, you can buy one online for around $20.
A signal source that you want to measure. This can be anything that produces an electrical signal, such as a battery, a speaker, a microphone, a sensor, etc.
A free copy of Zelscope that you can download from here.
How to Set Up Zelscope
Once you have downloaded and installed Zelscope on your computer, you need to set it up properly before using it as a USB oscilloscope software for free. Here are the steps to follow:
Launch Zelscope and click on the "Options" menu.
Select the "Audio Device" tab and choose the sound card or audio device that you are using as your input source.
Select the "Calibration" tab and click on the "Calibrate" button. This will help Zelscope adjust to the characteristics of your sound card or audio device.
Select the "Scope" tab and adjust the settings according to your preferences. You can change the time base, the voltage scale, the trigger mode, the grid size, etc.
Select the "Spectrum" tab and adjust the settings according to your preferences. You can change the frequency range, the resolution, the window function, etc.
Click on the "OK" button to save your settings and close the options menu.
How to Use Zelscope
Now that you have set up Zelscope, you are ready to use it as a USB oscilloscope software for free. Here are the steps to follow:
Connect your probe to the audio input of your sound card or audio device. Make sure that the resistor is connected between the tip and the ring of the 3.5 mm jack. This will prevent damage to your sound card or audio device.
Connect the alligator clips of your probe to the signal source that you want to measure. For example, if you want to measure the voltage of a battery, connect one clip to the positive terminal and one clip to the negative terminal.
Switch on your signal source and observe the waveform on Zelscope's scope window. You can use the buttons on the toolbar to zoom in or out, pause or resume, save or print, etc.
If you want to analyze the frequency spectrum of your signal source, switch to Zelscope's spectrum window. You can use the buttons on the toolbar to zoom in or out, pause or resume, save or print, etc.
If you want to perform calculations on your signal source, switch to Zelscope's calculator window. You can use the buttons on the toolbar to select different functions, such as peak-to-peak voltage, 04f6b60f66
