RIGOL Digital Oscilloscope DHO924 250MHz 12 bit 1.25 GSa/s 4 Channel

Description

Product Overview

The RIGOL DHO924 is a high‑performance digital oscilloscope designed for professionals who demand precision, reliability, and flexibility in their measurement tools. Featuring a 250 MHz analog bandwidth, the instrument captures fast‑changing signals with exceptional clarity, while the 12‑bit vertical resolution delivers a deep dynamic range that reveals subtle variations in amplitude. Its maximum real‑time sampling rate of 1.25 GSa/s across four independent analog channels enables simultaneous observation of multiple waveforms, making it ideal for complex circuit analysis, signal integrity testing, and educational labs.

Built on a robust chassis, the DHO924 incorporates a high‑speed ADC architecture that minimizes quantization noise and preserves signal fidelity. The front panel hosts intuitive controls, including a new flex knob that provides smooth, precise adjustments for vertical scale, time base, and trigger settings. The device is equipped with USB Device & Host, LAN, and HDMI ports, allowing seamless data transfer, remote control, and high‑definition video output to external displays. A comprehensive software suite supports online firmware upgrades, waveform analysis, and custom scripting, ensuring the oscilloscope remains up‑to‑date with evolving industry standards.

Physical specifications include a compact footprint of 10.5 × 6.4 × 3.0 inches and a weight of 3.9 lb, facilitating easy placement on crowded workbenches or transport between field sites. The package includes a power cable, USB cable, ground wire, and four high‑quality probes, providing everything needed to start measurements immediately out of the box.

Usage

The DHO924 excels in a wide range of applications, from laboratory research and product development to field service and classroom instruction. In electronics design, engineers rely on its fast sampling and high resolution to debug high‑speed digital interfaces, evaluate analog filter performance, and verify timing margins. Service technicians use the four‑channel capability to monitor power supplies, motor drives, and communication lines simultaneously, reducing diagnostic time and improving first‑time‑right rates.

Educational institutions benefit from the oscilloscope’s user‑friendly interface and comprehensive teaching tools, such as built‑in waveform generators, histogram analysis, and real‑time brightness functions. Students can explore fundamental concepts like Fourier transforms, signal modulation, and noise analysis without needing additional hardware. The HDMI output allows instructors to project live waveforms onto large screens, fostering interactive learning environments.

For field measurements, the DHO924’s rugged construction and low‑profile design make it suitable for on‑site troubleshooting of automotive electronics, aerospace systems, and industrial automation equipment. The LAN connectivity enables remote monitoring and control via a laptop or tablet, allowing engineers to capture data from hazardous or hard‑to‑reach locations safely.
