The Rigol DHO1072 is a 2-channel digital oscilloscope delivering 70 MHz bandwidth and 12-bit vertical resolution for precision signal acquisition and analysis. Native 12-bit resolution provides 16 times the quantization levels of conventional 8-bit instruments; high-resolution mode extends this to 16-bit for detection of subtle signal variations. Built on Rigol’s UltraVision III platform with a dedicated ASIC chipset, the DHO1072 captures waveforms at 2 GSa/s real-time sampling with up to 50 Mpts memory (expandable to 100 Mpts). The instrument achieves ≤5 ns rise time and operates an ultra-low noise floor for accurate small-signal measurement. A 10.1-inch HD touchscreen (1280 x 800 pixels) with Flex Knobs and photoelectric encoders enables intuitive operation on the benchtop.
