DHO1072 2 + EXT 70 MHz 12 bit 2 GSa/s
DHO1074 4 + EXT 70 MHz 12 bit 2 GSa/s
DHO1102 2 + EXT 100 MHz 12 bit 2 GSa/s
DHO1104 4 + EXT 100 MHz 12 bit 2 GSa/s
DHO1202 2 + EXT 200 MHz 12 bit 2 GSa/s
DHO1204 4 + EXT 200 MHz 12 bit 2 GSa/s
12 bit resolution – 16x improvement in quantization uncertainty
RIGOL’s latest oscilloscope technology includes a new custom chipset design enabling sampling with true 12 bit resolution. This reduces the quantization level between bits by a factor of 16. These high resolution samples improve signal fidelity and analysis capabilities for signals from power to communications.
Low noise
Rigol’s new ASIC chipset with dramatically lower front end noise makes the most of 12 bit analog to digital converters with a significantly lower noise floor. With the noise reduced by a factor of 5 compared to UltraVision II oscilloscopes, analyze smaller signal artifacts with a combination of speed and accuracy.
Ultra Acquire Burst Capture
Capture and visualize events at up to an equivalent rate of 1.5 million waveforms per second. Set your frame number to capture and visualize using a density, waterfall, perspective, or mosaic display. Utilize UltraAcquire to capture small, dynamic changes within a complex signal.
Useful long memory – Record, navigate, and analyze with flexible memory
With up to 100 Million points in a single capture, use the deep memory to record events, navigate long continuous captures, or even further reduce the noise with high resolution mode. Work with the deep memory using precision measurements for complete signal analysis.
Standard memory is 50Mpts, it can be increased to 100Mpts with option DHO1000-RLU-01.
Applications

An oscilloscope is an important tool for making power supply measurements. With up to 12-bit vertical resolution, the DHO1000 series makes it easy for you to perform ripple measurement and quality test.
This series redefines what you can expect in an entry-level oscilloscope by providing excellent noise performance and 12-bit high resolution, providing basic functionality for higher education.
The 10.1-inch large HD touch display enables better view of signals. Large memory depth and the Autoscale function make it ready for testing of embedded system designs.
With standard CAN and LIN serial decoding functions, it provides a more affordable solution for automotive electronics testing.
