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 Siglent Technologies SDS1104X-E is a solid choice for those looking into digital oscilloscopes, particularly for hobbyists and professionals who need versatile and reliable performance. With a bandwidth of 100 MHz and a decent sample rate, this oscilloscope is equipped to handle a variety of signal measurements. It supports four channels, making it useful for more complex analyses where multiple signals need to be monitored simultaneously. The addition of a standard decoder for protocols like IIC, SPI, UART, CAN, and LIN enhances its functionality, especially in embedded system projects.

One of the standout features is the memory depth, allowing for detailed signal captures, which is essential for analyzing fast signals over time. The display quality is generally good, contributing to a user-friendly experience when interpreting waveforms. Furthermore, with the option for a USB AWG module, it adds even more flexibility for users who may need signal generation capabilities alongside their measurements.

The weight of 6.6 pounds may make it less portable than some users would prefer, particularly for those who might need to transport it frequently. Additionally, while it caters well to common protocols, it may lack specialized decoding for less common protocols, which could be a limitation for some advanced users. The model has been in the market since 2017, so while it remains relevant, it may not have the latest technology features found in newer models.

The SDS1104X-E digital oscilloscope is a well-rounded instrument for those who require a reliable tool for everyday signal analysis in an industrial, scientific, or educational setting. It balances features and performance effectively, although potential users should consider their specific needs, especially regarding portability and protocol decoding capabilities.

The RIGOL Digital Oscilloscope DHO924S is a solid choice for users who need a reliable tool for electronics testing and signal analysis, particularly in educational, hobbyist, or light industrial settings. With a bandwidth of 250 MHz and a maximum sample rate of 1.25 GSa/s, it offers impressive capabilities for capturing and analyzing a range of signals. The four analog channels mean you can monitor multiple signals simultaneously, which is especially useful in complex tasks.

One of the standout strengths is the 12-bit vertical resolution, providing clear and detailed signal representation. The ultra-low background noise enhances the purity of the signals you capture, making it easier to work with small signals that might be missed with other oscilloscopes. Additionally, the scope's high-definition 7-inch touch screen enhances user experience, allowing for intuitive navigation and display of data.

However, there are some drawbacks to consider. While it’s robust in features, the learning curve might be steep for beginners unfamiliar with oscilloscope functions, despite the user-friendly Flex knob designed to simplify operation. The model also weighs around 3.9 lbs, which is relatively lightweight, but may still be cumbersome for portable use in various environments. Lastly, while it supports a variety of advanced features such as waveform navigation and digital signal analysis, users who need extensive customization or advanced analysis might find the capabilities somewhat limited compared to higher-end models.

The RIGOL DHO924S is well-suited for those needing a dependable and feature-rich digital oscilloscope without entering the high-end price range. Its combination of performance and usability makes it ideal for students, hobbyists, and professionals who require a versatile tool for electronics troubleshooting and design.
