10 Best Digital Oscilloscopes 2025 in the United States

The RIGOL Digital Oscilloscope DHO814 is designed for professionals and hobbyists who need reliable performance in a compact package. With a bandwidth of 100 MHz and up to 1.25 GSa/s sample rate, it meets the demands of various applications, from basic electronics to more complex signal analysis. The device's 12-bit vertical resolution enhances the clarity of signals, allowing for better observation of small fluctuations that may otherwise go unnoticed.

One of its standout features is the support for up to four analog channels, enabling users to analyze multiple signals simultaneously, which is a significant advantage in complex diagnostic scenarios. The 25 Mpts memory depth allows for capturing longer signals without losing detail, making it ideal for applications requiring extensive data capture. The user-friendly 7-inch touchscreen display coupled with the innovative Flex knob improves usability significantly, making navigation through options intuitive.

However, there are some drawbacks to consider. While the 100 MHz bandwidth is sufficient for many applications, professionals working with higher frequency signals may find it limiting. Additionally, though the waveform search and navigation functions are beneficial, they may have a learning curve for beginners. There are also some competitors that offer higher specifications at a similar price point, which could be a consideration for users wanting the latest features.

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.
