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 SDS1104X-E is a solid choice for those looking into digital oscilloscopes, particularly for hobbyists and professionals who need versatile and reliable performance. With a bandwidth of 100 MHz and a decent sample rate, this oscilloscope is equipped to handle a variety of signal measurements. It supports four channels, making it useful for more complex analyses where multiple signals need to be monitored simultaneously. The addition of a standard decoder for protocols like IIC, SPI, UART, CAN, and LIN enhances its functionality, especially in embedded system projects.

One of the standout features is the memory depth, allowing for detailed signal captures, which is essential for analyzing fast signals over time. The display quality is generally good, contributing to a user-friendly experience when interpreting waveforms. Furthermore, with the option for a USB AWG module, it adds even more flexibility for users who may need signal generation capabilities alongside their measurements.

The weight of 6.6 pounds may make it less portable than some users would prefer, particularly for those who might need to transport it frequently. Additionally, while it caters well to common protocols, it may lack specialized decoding for less common protocols, which could be a limitation for some advanced users. The model has been in the market since 2017, so while it remains relevant, it may not have the latest technology features found in newer models.

The SDS1104X-E digital oscilloscope is a well-rounded instrument for those who require a reliable tool for everyday signal analysis in an industrial, scientific, or educational setting. It balances features and performance effectively, although potential users should consider their specific needs, especially regarding portability and protocol decoding capabilities.

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.
