Description

RIGOL DHO1202 is a high-performance 2-channel high-resolution oscilloscope based on RIGOL's new Centaurus chipset and equipped with a 10.1" 1280×800 HD touch display with an interactive user-friendly interface and a double multi-function knob design for smoother interaction. The RIGOL DHO1202 offers a bandwidth of 200 MHz, a real-time sample rate of up to 2 GSa/s, a waveform capture rate of up to 1,500,000 wfms/s in UltraAcquire mode, and a memory depth of 50 Mpts (expandable to 100 Mbts as an option). Two analog channels and an additional external channel ensure versatile signal analysis, while the 12-bit vertical resolution enhances the accuracy and fidelity of captured waveforms.

RIGOL DHO1202 maintains an ultralow noise floor for cleaner signals, 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 to simplify the analysis of communication signals and facilitate protocol debugging. The RIGOL DHO1202's extensive range of features, including a fast waveform capture rate, low noise floor, large memory depth, intuitive touch display, and an effortless user experience, make it well-suited for mainstream designing, debugging, and testing applications.
