10 Best Digital Oscilloscopes 2026 in the United States

The Tektronix TBS2204B is a digital storage oscilloscope designed for users who require precision and versatility in their measurements. With a bandwidth of 200 MHz and a sampling rate of 2 GS/s, it offers a solid performance for a variety of electronic applications, making it suitable for both professionals and advanced hobbyists. The four analog channels allow users to observe multiple signals simultaneously, which is particularly beneficial when troubleshooting complex circuits.

One of the standout features is the 5 M record length on all channels, providing ample memory for capturing longer signal events. This is great for detailed analysis without missing crucial data. The 9-inch WVGA color display is another strong point, offering 50% more horizontal grids compared to many competitors, which enhances visibility and makes it easier to analyze waveforms clearly.

There are some drawbacks to consider. At 39.68 pounds, the oscilloscope is relatively heavy and might not be ideal for portable use or for those needing a device that can be easily transported. Additionally, while the specifications are impressive, beginners might find the professional-grade features overwhelming, as they require a certain level of expertise to fully utilize.

The FNIRSI DPOS350P is a versatile handheld oscilloscope that combines four tools in one: a 350 MHz bandwidth oscilloscope, a spectrum analyzer, a frequency response analyzer, and a DDS signal generator. With its 1 GSa/s sample rate and 2 channels, it covers many basic and intermediate testing needs, making it a good fit for electronics hobbyists, students, and field technicians who require portability and multifunctionality. The 7-inch touchscreen with digital phosphor display offers clear visuals and easy interaction, which is helpful if you prefer a tablet-like experience.

It also includes smart features like the ability to store 500 waveforms and 90 screenshots, as well as USB-C charging with an 8000 mAh battery, making it suitable for extended use away from a lab. On the downside, the memory depth of 60 Kpts is moderate, meaning very long signal captures might be limited compared to larger benchtop scopes. While the handheld form factor is great for mobility, it may not replace full-sized oscilloscopes for very detailed or specialized lab work.

The spectrum analyzer and frequency response analyzer functions add extra value, especially for users needing signal integrity and filter analysis. This device provides a solid balance of features and portability for those who want more than just a basic oscilloscope, but don’t require high-end lab equipment.

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.
