The Rigol DHO1204 is a 4-channel digital oscilloscope delivering 200 MHz analog bandwidth with 12-bit vertical resolution and high-speed signal acquisition. Built on the UltraVision III platform with custom ASIC design, this instrument captures waveforms at up to 1,500,000 wfms/s in UltraAcquire Mode and maintains an ultra-low noise floor for accurate measurement of small-amplitude signals. The DHO1204 combines high vertical fidelity, deep memory, and intuitive controls in a compact benchtop form factor.
