10 Best Digital Oscilloscopes 2025 in the United States

The RIGOL Digital Oscilloscope DHO804 is a versatile and feature-packed device, perfect for professionals and enthusiasts in the electronics field. It offers a 70MHz bandwidth, which is sufficient for analyzing a wide range of signals. The sample rate of 1.25 GSa/s ensures high-resolution signal capture, and with 12-bit vertical resolution, it provides more detailed and accurate measurements compared to many 8-bit oscilloscopes on the market. The four analog channels allow for multi-signal analysis, making it a handy tool for complex troubleshooting and development tasks.

The memory depth of up to 25 Mpts means you can store extensive data for in-depth analysis. The oscilloscope's ultra-low background noise and high waveform capture rate (up to 1 million wfms/s) help to detect even the smallest signal anomalies, enhancing its reliability and precision. The 7-inch HD touch screen enhances the user experience with clear visuals and intuitive controls. Connectivity options including USB, LAN, and HDMI ports offer flexibility for data transfer and external display connections.

The compact form factor and lightweight design make it portable and easy to handle. However, the 70MHz bandwidth might be limiting for users who need to analyze higher frequency signals. Additionally, while the device supports a high-definition display and interactive controls, it might have a learning curve for beginners unfamiliar with advanced oscilloscopes. The 3-year warranty provides peace of mind, ensuring durability and long-term reliability. Accessories like probes, power cable, and USB cable are included, making it ready to use out of the box. This oscilloscope is a solid choice for those looking for a mid-range option with robust features and dependable performance.

The Hantek DSO2D15 is a budget-friendly digital oscilloscope designed for users needing solid performance without a high price tag. Its 150MHz bandwidth and 1GSa/s sample rate allow you to capture and analyze signals with decent detail. With 2 channels, it’s suitable for comparing or monitoring two signals at once, fitting typical lab or field work needs. The 8M memory depth is generous for this price range, meaning it can store longer waveforms for thorough analysis.

One standout feature is the built-in waveform generator, which adds extra versatility for testing and signal creation. The oscilloscope supports various triggering modes—including 14 types and several serial protocol triggers—helping you catch specific events accurately. The device has a reasonably compact and portable form factor, weighing about 4.2 pounds, making it manageable for carrying between workstations or field sites.

This model suits a wide range of users from students and hobbyists to professionals in communications, aerospace, or embedded systems who need reliable but affordable test equipment. While it lacks some advanced features found in higher-end scopes, such as a larger or more modern display and extensive connectivity options like USB or LAN for easy data transfer, the Hantek DSO2D15 represents a balanced, capable, and cost-effective oscilloscope for general purpose signal observation and testing.
