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 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.
