SKU: 911616 Category:

The RIGOL HDO4204 oscilloscope, a member of the HDO4000 series, is designed to meet the requirements of the mainstream oscilloscope market. The 4-channel high-resolution oscilloscope features a 10.1″ 1280×800 HD touch display, providing a clear and interactive user-friendly interface, and offers a bandwidth of 200 MHz, a real-time sample rate of up to 4 GSa/s, and waveform capture rate of up to 1,500,000 wfms/s in UltraAcquire mode. 4 analog channels and an additional EXT channel ensure versatile signal analysis, while the 12-bit vertical resolution enhances the accuracy and fidelity of captured waveforms. The oscilloscope’s memory depth can be expanded up to 500 Mpts for an ample storage capacity for waveform data. RIGOL HDO4204 maintains an ultra-low noise floor of 18 μVrms at minimum settings, enabling precise measurements even in low-amplitude scenarios, and includes built-in serial decoders for popular protocols such as I²C, SPI, RS232/UART, and CAN, which simplifies the analysis of communication signals and facilitates protocol debugging.

RIGOL HDO4204 is a versatile and high-performance instrument. Its comprehensive range of features, including the powerful Centaurus chipset, fast waveform capture rate, large memory depth, low noise floor, intuitive touch display, make it a perfect choice for accurate measurements, design analysis, and debugging tasks in various applications and ensure an exceptional testing experience.
