The Rigol DHO4204 is a 4-channel digital oscilloscope delivering 200 MHz bandwidth and 12-bit vertical resolution for precision signal analysis across design, debugging, and test environments. Built on Rigol’s Centaurus chipset, this instrument captures waveforms at up to 1,500,000 wfms/s in UltraAcquire mode and achieves an ultra-low noise floor of 18 µVrms minimum. The 10.1-inch HD capacitive touchscreen display provides intuitive control via Flex Knobs and dual multi-function encoders, while dual input impedance options (1 MΩ and 50 Ω) support diverse measurement scenarios.
