10 Best Digital Oscilloscopes 2025 in the United States

The Fluke 190-204/AM/S is a handheld digital oscilloscope with four channels and a 200 MHz bandwidth, making it suitable for professionals who need to capture and analyze multiple electrical signals simultaneously. Its real-time sample rate is 2.5 GS/s, which helps in accurately displaying fast-changing signals, and the memory depth of 10,000 points per channel allows detailed waveform recording. The 6-inch color LCD is large enough to view up to four waveforms or measurements at once, which is helpful for clear analysis on the go.

It also features handy tools like zoom, math functions including FFT for frequency analysis, and automatic measurements to simplify signal interpretation. Safety ratings for use in high-voltage environments (CAT III 1000V and CAT IV 600V) make it reliable for industrial settings. One thing to note is its weight—about 16 pounds—which is heavier than many portable scopes, so it might feel bulky during extended handheld use.

This oscilloscope represents a strong choice for technicians seeking a rugged, multi-channel instrument with good bandwidth and sample rate, especially when working in demanding environments.

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.

The RIGOL Digital Oscilloscope DHO924S is a solid choice for users who need a reliable tool for electronics testing and signal analysis, particularly in educational, hobbyist, or light industrial settings. With a bandwidth of 250 MHz and a maximum sample rate of 1.25 GSa/s, it offers impressive capabilities for capturing and analyzing a range of signals. The four analog channels mean you can monitor multiple signals simultaneously, which is especially useful in complex tasks.

One of the standout strengths is the 12-bit vertical resolution, providing clear and detailed signal representation. The ultra-low background noise enhances the purity of the signals you capture, making it easier to work with small signals that might be missed with other oscilloscopes. Additionally, the scope's high-definition 7-inch touch screen enhances user experience, allowing for intuitive navigation and display of data.

However, there are some drawbacks to consider. While it’s robust in features, the learning curve might be steep for beginners unfamiliar with oscilloscope functions, despite the user-friendly Flex knob designed to simplify operation. The model also weighs around 3.9 lbs, which is relatively lightweight, but may still be cumbersome for portable use in various environments. Lastly, while it supports a variety of advanced features such as waveform navigation and digital signal analysis, users who need extensive customization or advanced analysis might find the capabilities somewhat limited compared to higher-end models.

The RIGOL DHO924S is well-suited for those needing a dependable and feature-rich digital oscilloscope without entering the high-end price range. Its combination of performance and usability makes it ideal for students, hobbyists, and professionals who require a versatile tool for electronics troubleshooting and design.
