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 GW Instek MDO-2204EX is a versatile digital oscilloscope with a bandwidth of 200 MHz, which is suitable for a range of applications including both basic and more demanding signal analysis tasks. It features four channels, allowing for simultaneous measurement of multiple signals, which can be particularly useful in complex diagnostic scenarios.

The oscilloscope also includes a spectrum analyzer, a dual-channel 25 MHz arbitrary waveform generator (AWG), a 5,000 counts digital multimeter (DMM), and a power supply, making it a comprehensive tool for electronics workstations. The integration of these additional tools eliminates the need for separate devices, saving both space and cost.

With dimensions of 5.01 x 15.12 x 8.19 inches and weighing 10.14 pounds, it is relatively portable but might be on the heavier side for some users. This oscilloscope should appeal to both professionals and hobbyists looking for a multifunctional instrument.

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.
