RIGOL DHO1104 is a high-performance 4-channel high-resolution oscilloscope featuring a 10.1″ 1280×800 HD touch display with an interactive user-friendly interface, a bandwidth of 100 MHz, a real-time sample rate of up to 2 GSa/s, and waveform capture rate of up to 1,500,000 wfms/s in UltraAcquire mode. Four 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 100 Mpts for an ample storage capacity for waveform data.
RIGOL DHO1104 maintains a low noise floor 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 to simplify the analysis of communication signals and facilitate protocol debugging.
