10 Best Digital Oscilloscopes 2025 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 GW Instek MDO-2204EX is a versatile digital oscilloscope with a bandwidth of 200 MHz, which is suitable for a range of applications including both basic and more demanding signal analysis tasks. It features four channels, allowing for simultaneous measurement of multiple signals, which can be particularly useful in complex diagnostic scenarios.

The oscilloscope also includes a spectrum analyzer, a dual-channel 25 MHz arbitrary waveform generator (AWG), a 5,000 counts digital multimeter (DMM), and a power supply, making it a comprehensive tool for electronics workstations. The integration of these additional tools eliminates the need for separate devices, saving both space and cost.

With dimensions of 5.01 x 15.12 x 8.19 inches and weighing 10.14 pounds, it is relatively portable but might be on the heavier side for some users. This oscilloscope should appeal to both professionals and hobbyists looking for a multifunctional instrument.

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.
