10 Best Digital Oscilloscopes 2025 in the United States

The Hantek DSO2D15 is a budget-friendly digital oscilloscope designed for users needing solid performance without a high price tag. Its 150MHz bandwidth and 1GSa/s sample rate allow you to capture and analyze signals with decent detail. With 2 channels, it’s suitable for comparing or monitoring two signals at once, fitting typical lab or field work needs. The 8M memory depth is generous for this price range, meaning it can store longer waveforms for thorough analysis.

One standout feature is the built-in waveform generator, which adds extra versatility for testing and signal creation. The oscilloscope supports various triggering modes—including 14 types and several serial protocol triggers—helping you catch specific events accurately. The device has a reasonably compact and portable form factor, weighing about 4.2 pounds, making it manageable for carrying between workstations or field sites.

This model suits a wide range of users from students and hobbyists to professionals in communications, aerospace, or embedded systems who need reliable but affordable test equipment. While it lacks some advanced features found in higher-end scopes, such as a larger or more modern display and extensive connectivity options like USB or LAN for easy data transfer, the Hantek DSO2D15 represents a balanced, capable, and cost-effective oscilloscope for general purpose signal observation and testing.

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.
