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.
