Rigol DS4012 Digital Oscilloscope 100Mhz 4 Gsa/S Bandwidth 2 Analog Channels

The Rigol DS4012 is a 100 MHz, 2-channel digital storage oscilloscope engineered for precise signal capture and analysis. It delivers real-time sampling at 4 GSa/s with 140 Mpts memory depth per channel, enabling detailed waveform acquisition and extended data stream investigation. The instrument captures up to 110,000 waveforms per second via UltraVision technology, supporting real-time recording, replay, and analysis of up to 200,000 frames.

Its 9-inch WVGA color LCD display (800 × 480 pixels, 256 intensity levels) presents clear, vivid waveform visualization across a wide range of test scenarios.
