The Rigol DHO1102 is a 2-channel digital oscilloscope delivering 100 MHz bandwidth and 12-bit vertical resolution (expandable to 16-bit in high-resolution mode) for precision signal capture in lab and field environments. Built on Rigol’s proprietary Centaurus chipset, the instrument achieves real-time sampling to 2 GSa/s, an ultra-low noise floor, and waveform capture rates up to 1,500,000 wfms/s in UltraAcquire mode. The 10.1-inch HD capacitive touchscreen (1280 × 800 pixels) provides intuitive navigation and clear waveform visualization across measurement ranges from 500 μV/div to 10 V/div.
