Product Information
Full details
The Voltcraft DSO-2020 USB Oscilloscope is designed for electronics enthusiasts and professionals using Windows-based computers for signal visualization and analysis. Its key benefit is providing a fully functional Digital Storage Oscilloscope (DSO) experience through a USB 2.0 connection, offering two independent input channels. A potential caveat is its reliance on a Windows PC for operation.

FAQs
What operating systems are compatible with the DSO-2020?
The Voltcraft DSO-2020 is designed to work with Windows-based operating systems. Please refer to the software documentation for specific version compatibility.
Can I use this oscilloscope with a Mac or Linux computer?
No, the DSO-2020 requires the specific Windows measurement software and is not compatible with macOS or Linux operating systems.
What is the maximum frequency I can measure?
The oscilloscope has a bandwidth of 20 MHz, meaning it can accurately measure signals up to approximately 20 MHz. Signals significantly above this frequency may be attenuated or distorted.
How do I connect the probes?
The probes connect to the BNC connectors labeled CH1 and CH2 on the front panel of the DSO-2020. Ensure a secure connection.
Can I save the waveforms I capture?
Yes, the included measurement software allows you to save captured waveforms in various formats, such as image files or data files, for later analysis or reporting.
Does it come with software?
Yes, the oscilloscope comes with the necessary measurement software on an included CD, or it can typically be downloaded from the manufacturer's website.
What is the sampling rate?
The sampling rate is 48 MS/s (Mega Samples per second), which determines how frequently the oscilloscope samples the input signal.
Troubleshooting
Device not recognized by the computer
Ensure the USB cable is securely connected to both the DSO-2020 and the PC. Try a different USB port, preferably directly on the motherboard. Verify that the correct drivers are installed via the software installation.
No waveform displayed
Check that the probes are correctly connected to the input channels and the signal source. Ensure the signal source is active. Verify that the software is configured to display the active channel and that the trigger settings are appropriate for the signal.
Inaccurate measurements
Calibrate the oscilloscope using the provided software function if available. Ensure the probe attenuation setting (x1 or x10) in the software matches the setting on the probe itself. Check for ground connections.
Software crashes or freezes
Close and reopen the software. Restart your computer. Ensure you are running the latest version of the software and that your Windows operating system is up to date. Check for conflicts with other running software.
Pros and Cons
Pros
- Provides a cost-effective entry into digital oscilloscope functionality.
- Leverages a PC's screen for clear, large waveform display.
- Dual-channel capability allows for comparative signal analysis.
- Signal capture and export features aid in documentation and further analysis.
- Includes automatic measurement functions for efficiency.
Cons
- Requires a Windows-based computer for operation.
- Limited bandwidth (20 MHz) may not be sufficient for high-frequency applications.
- Sampling rate (48 MS/s) might limit resolution for very fast transient signals.
- Performance is dependent on the host computer's USB capabilities and processing power.
- Reliance on software means updates and compatibility can be factors.
Setup, Compatibility & Care
Setup:
- Install Software: Insert the included software CD or download the latest version from the manufacturer's website and install the measurement program on your Windows PC.
- Connect Oscilloscope: Connect the Voltcraft DSO-2020 to a USB 2.0 port on your computer using the provided USB cable.
- Connect Probes: Attach your BNC-terminated oscilloscope probes to the two input channels (CH1 and CH2) on the front of the DSO-2020.
- Launch Software: Open the installed measurement program on your PC.
- Configure Channels: Ensure the software recognizes the hardware and select the appropriate input settings for your probes (e.g., x1 or x10).
Compatibility:
- Operating System: Requires a Windows-based operating system. Check software documentation for specific version compatibility (e.g., Windows 7, 8, 10, 11).
- USB Port: Requires a functional USB 2.0 port.
Care:
- Cleaning: Keep the unit clean by wiping it with a dry, lint-free cloth. Avoid using liquids or abrasive cleaners.
