DHO800 Series RIGOL Digital Oscilloscopes

The Dawn of Precision: Introducing the DHO800 Series

The digital oscilloscope has long been the cornerstone of electronic design and troubleshooting, acting as the eyes of engineers and hobbyists alike by visualizing complex electrical signals. The RIGOL DHO800 series emerges as a revolutionary entry into this essential market, challenging the traditional trade-offs between performance and affordability. This new line of high-performance, economical digital oscilloscopes redefines what users can expect from a compact device. It brings superior technology, including an exceptionally low noise floor and a groundbreaking 12-bit resolution, into a form factor that is both portable and powerful. This series is not merely an incremental update; it’s a complete rethinking of the core features necessary for modern design, debugging, and testing. With its state-of-the-art capabilities and user-centric design, the DHO800 series is set to become the go-to tool for a broad spectrum of professionals and enthusiasts.

Unmatched Clarity with an Ultra-Low Noise Floor

One of the most significant advancements of the DHO800 series is its ultra-low noise floor, a feature that fundamentally alters how users can interact with signals. In essence, a noise floor is the level of unwanted electrical noise inherent in the instrument itself. A low noise floor means that the oscilloscope can distinguish between minute, genuine signal fluctuations and the background noise, providing a purer, more accurate representation of the waveform. This is particularly crucial for applications where small signals or subtle anomalies are key to diagnosis. Imagine trying to hear a whisper in a noisy room; the DHO800 series is like a high-fidelity microphone that eliminates the room’s hum, allowing you to clearly hear every detail of the whisper. This enhanced clarity ensures that even the most fleeting and intricate signal components are captured, empowering engineers to debug complex issues with unparalleled confidence and precision.

Capturing the Ephemeral: High-Speed Acquisition

The ability to capture transient events is paramount in many modern electronic fields. The DHO800 series excels in this regard with an astounding maximum capture rate of 1,000,000 wfms/s in its innovative UltraAcquire mode. This is not just a number; it represents the oscilloscope’s ability to refresh the screen incredibly fast, effectively acting like a high-speed camera for electrical signals. This rapid waveform capture rate is critical for identifying rare or intermittent glitches that might otherwise be missed by a slower instrument. In addition, its impressive 25 Mpts memory depth allows for the capture of long signal streams at high resolution. This combination of speed and depth means you can zoom in on specific sections of a waveform, analyze complex protocols, and track down elusive anomalies with ease, making the DHO800 an indispensable tool for advanced debugging.

A User Experience Redefined with Flex Knob

Beyond its raw technical specifications, the DHO800 series stands out for its thoughtful and innovative user experience. At the heart of this design is the brand-new Flex Knob, a control that goes beyond the traditional rotary encoder. This intuitive, multi-function knob simplifies navigation and parameter adjustments, making the oscilloscope more approachable and efficient to use. Instead of fumbling through multiple menus, the Flex Knob provides a fluid, tactile interface for adjusting settings like vertical sensitivity or time base. This physical control is complemented by a large 7-inch (1024×600) capacitive multi-touch screen, which supports familiar gestures like pinch-to-zoom and swipe. The blend of a physical knob and a responsive touchscreen creates a dynamic and user-friendly interface that dramatically reduces the learning curve and streamlines the workflow for engineers of all experience levels.

The Unrivaled Versatility of this Product

The DHO800 series is not just for one specific type of user; its versatility makes it an essential tool across a multitude of applications. For power electronics, its low noise floor and high voltage probe support (e.g., RP1018H) allow for safe and accurate analysis of power supply circuits and inverters. In automotive electronics, the integrated serial bus decoding for CAN and RS232/UART is invaluable for debugging vehicle communication networks. For embedded systems design, the high memory depth and multi-channel capability are perfect for analyzing complex digital logic and identifying timing issues between signals. Its robust trigger types—from edge and pulse to advanced patterns—enable users to isolate and capture specific events, no matter how complex the conditions. The DHO800’s adaptability and comprehensive feature set make it a foundational instrument for anyone working with electronic signals, from professional R&D to educational labs.

A Comprehensive Toolkit for In-Depth Analysis

The DHO800 series provides a comprehensive suite of analytical tools that empower users to go beyond simple waveform viewing. The waveform search and navigation function, for instance, allows for quick identification of signal anomalies, saving countless hours of manual searching. This is particularly useful for long-duration captures, where a single glitch might be hidden within millions of data points. The instrument also features a powerful digital phosphor display with 256 levels of intensity grading, which visualizes the frequency of signal occurrences over time, making it easier to spot subtle jitter and noise. Paired with extensive measurement and math functions, including FFT for frequency domain analysis, the DHO800 series is not just a measurement device; it’s a complete analysis workstation in a compact package.

Expanding Capabilities with Supported Probes

The true potential of any oscilloscope is unlocked by its ecosystem of accessories. The DHO800 series is compatible with a wide range of RIGOL probes and accessories, allowing users to expand their measurement capabilities to fit any application. For general-purpose use, the PVP2150 and PVP2350 high-impedance probes provide reliable performance with switchable attenuation. When dealing with high-voltage environments, the RP1018H and RP1300H high-voltage probes offer a safe and accurate solution, while the PHA series of high-voltage differential probes (like the PHA2150) are essential for floating measurements in power electronics. For current measurement, the RP1000C series of current probes offers a non-intrusive way to analyze current flow in circuits. This extensive compatibility ensures that the DHO800 series can be configured for almost any task, from simple signal tracing to advanced power integrity analysis.
