An oscilloscope is a device that measures and analyses signals in circuits. It's an indispensable equipment for everyone who works with electronic circuits since it enables them to see the activity of a wave in real - time basis. The DSO138 is one of the most popular oscilloscopes on the market today. We'll give a general description of the DSO138 and describe how to utilise it in this post.
What is the DSO138?
The DSO138 is a portable oscilloscope which is cheap and well-liked among electronics amateurs. Since it is a digital oscilloscope, the output is shown on the screen using digital signal processing techniques. The DSO138 is very simple to use, with an easy interface. The easy interface makes it ideal for novices.
The 2.4-inch TFT colour display on the DSO138 features a 320 x 240 pixel resolution. It can show signals with a highest sampling rate of 1Msps and a bandwidth of up to 200kHz. With a 1M input impedance, the DSO138 is adequate for the majority of applications. A 9V battery or a DC power source can power it.
How to Use the DSO138
Using the DSO138 is relatively straightforward. Here are the steps to follow:
Step 1: Connect the Probe
Connect the probe to the input connector on the DSO138. The probe has a ground clip and a probe tip. The ground clip should be connected to the ground of the circuit you want to measure, and the probe tip should be connected to the signal you want to measure.
Step 2: Power On the DSO138
Power on the DSO138 by connecting it to a 9V battery or a DC power supply.
Step 3: Adjust the Horizontal and Vertical Controls
Adjust the horizontal and vertical controls to set the time and voltage scales. The horizontal control adjusts the time scale, and the vertical control adjusts the voltage scale.
Step 4: Trigger the Signal
Press the trigger button to start capturing the signal. You can set the trigger level and slope using the trigger controls.
Step 5: Analyze the Signal
Examine the on-screen signal. The cursors may be used to calculate the voltage and time at various signal locations. The auto-measurement feature may be used to determine the signal's frequency, period, peak-to-peak voltage, and other characteristics.
Control Buttons of DSO138 Oscilloscope
The DSO138 oscilloscope has several button controls that are used to adjust and configure various settings on the device. Here's a brief explanation of each button control:
- Power Button
The power button is used to turn the oscilloscope on and off. When the oscilloscope is turned on, the power LED on the board will light up.
- Auto Button
The Auto button is used to activate the auto-setup function, which automatically configures the vertical and horizontal scales to display the signal on the screen. This is useful when you want to quickly set up the oscilloscope to view a signal without manually adjusting the scales.
- Cursor Button
The Cursor button is used to activate the cursor function, which allows you to measure the time and voltage of different points on the signal. The cursor function is activated by pressing the button, and the two cursors on the screen can be moved using the horizontal and vertical controls.
- Trigger Button
The Trigger button is used to activate the trigger function, which is used to stabilize the waveform on the screen. The trigger function is activated by pressing the button, and the trigger level and slope can be adjusted using the trigger controls.
- Time/Div Button
The Time/Div button is used to adjust the horizontal scale of the signal. Pressing the button allows you to cycle through different time/div settings, which change the amount of time displayed on the screen per division.
- Volts/Div Button
The Volts/Div button is used to adjust the vertical scale of the signal. Pressing the button allows you to cycle through different volts/div settings, which change the amount of voltage displayed on the screen per division.
- Menu Button
The Menu button is used to access the menu system, which allows you to adjust various settings on the oscilloscope. Pressing the button once displays the main menu, and pressing it again cycles through the different menu options.
- Reset Button
The Reset button is used to reset the oscilloscope to its default settings. This can be useful if you've made a lot of changes to the settings and want to start fresh.
The DSO138 oscilloscope button controls are easy to use and provide a range of different functions that allow you to adjust and configure the device to your needs. By understanding how each button control works, you can quickly and easily adjust the settings to view and analyze the signal on the screen.
