The Rigol DS1104B is a 4-channel, 100 MHz digital storage oscilloscope engineered for real-time signal acquisition and analysis across electronics, embedded systems, and service applications. It delivers 1 GSa/s real-time sample rate per channel (2 GSa/s across two channels) with 25 GSa/s equivalent-time sampling, supported by 16 kpts memory depth per channel. The 5.7-inch TFT LCD display with 320 × 234 pixel resolution and 65,536 colors renders waveforms and measurements with clarity across multiple trigger modes.
