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 SDS1204X HD is a solid choice for anyone needing a reliable digital oscilloscope with good performance. It offers a 200MHz bandwidth, which is suitable for a wide range of general electronics and industrial testing tasks. With 4 input channels, it lets you monitor multiple signals at once, which is handy for more complex circuits. The sample rate of 2GSa/s and memory depth of 100 million points ensure smooth and detailed waveform capture, making it easier to see subtle signal changes. Its 12-bit resolution improves measurement accuracy compared to many standard 8-bit scopes.

The large 10.1-inch touchscreen display with good resolution makes it comfortable to view and interact with waveforms. The high waveform capture rate helps catch intermittent signal issues quickly. The noise floor is impressively low, meaning clearer signal readings, especially at higher frequencies. One additional bonus is the option to add 16 digital channels if needed, though the required accessories are sold separately.

A downside is that the oscilloscope is somewhat heavy and bulky, so it’s less convenient for portable use. Also, advanced features and connectivity options are limited compared to higher-end models. This scope is well suited for hobbyists, engineers, and technicians who want a versatile, accurate instrument for everyday lab or bench work without delving into very specialized or high-frequency testing.

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.
