The Rigol DHO4804 is a 4-channel digital oscilloscope delivering 800 MHz bandwidth and 12-bit vertical resolution for high-fidelity signal analysis across debugging and electronic testing workflows. It captures complex signals with a 4 GSa/s real-time sample rate, 250 Mpts standard memory (expandable to 500 Mpts), and UltraAcquire technology enabling waveform capture rates up to 1,500,000 wfms/s to detect transient events. Built on RIGOL’s UltraVision III platform with the proprietary Centaurus chipset, the DHO4804 achieves an ultra-low noise floor of 18 µVrms and supports vertical sensitivity from 100 µV/div to 10 V/div across both 1 MΩ and 50 Ω input impedance modes.
