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 Siglent Technologies SDS1202X-E is a digital oscilloscope that stands out for its 200 MHz bandwidth, making it suitable for a wide range of applications, from basic electronics to more complex circuit analysis. With a real-time sampling rate of up to 1 GS/s, it captures fast signal changes effectively, which is a strong point for users needing accurate signal representation. The 14 Mpts memory depth allows for significant data collection, enabling users to analyze long signals without losing detail, which is particularly beneficial for troubleshooting and research work.

On the convenience side, it features two channels, allowing users to compare signals from different points within a circuit, enhancing its versatility. The standard serial bus triggering is a notable advantage, supporting various communication protocols such as IIC, SPI, UART, RS232, CAN, and LIN, making it a solid choice for those working with integrated systems.

While it offers good performance for its category, the display quality may not be as high as some premium models, which could impact visibility in certain lighting conditions. Additionally, being a product from China, some users may have concerns regarding long-term support and warranty services compared to brands with a more established presence in their region. The Siglent Technologies SDS1202X-E is well-suited for hobbyists, engineering students, and professionals looking for a reliable oscilloscope without a hefty price tag. Its balance of features and performance makes it a strong contender in the digital oscilloscope market, but potential buyers should consider their specific needs regarding display quality and after-sales support.

The Fluke 123B Industrial ScopeMeter is a sturdy and portable handheld oscilloscope designed mainly for industrial fieldwork. With two input channels and a 20 MHz bandwidth, it suits basic to moderate waveform analysis, especially for troubleshooting electrical signals in machinery and equipment. This model focuses on simplicity and durability rather than high-end lab capabilities. Its true-RMS digital multimeter functionality adds value by allowing precise voltage and current measurements alongside waveform capture.

The Connect-and-View and IntellaSet Auto Reading technologies help users quickly get accurate readings without deep oscilloscope expertise, which is excellent for technicians needing fast diagnostics. The seven-hour battery life with rechargeable Li-Ion battery is convenient for extended field use. The relatively low bandwidth means it might not meet demands for detailed signal analysis or complex triggering scenarios. The display details are minimal, likely adequate but not advanced.

Weighing just over 3 pounds and designed as a handheld unit, it’s portable but not pocket-sized. This device fits well for industrial technicians who prioritize ease of use, durability, and basic oscilloscope functions in the field, but it is less suitable for users needing high-speed sampling, deep memory, or advanced triggering features.
