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 -> New ASIC chipset with dramatically lower front end noise

Make 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 our UltraVision II Oscilloscopes analyze smaller signal artifacts with a combination of speed and accuracy. The HDO4000 has a 100 uV/div range setting with demonstrated noise as low as 18 uVrms with a 20 MHz bandwidth filter. Regardless of the level or signal speed, view more of the signal with the high signal fidelity of the HDO4000 Series.

Ultra Acquire Burst Capture -> Visualize dynamic signals with multiple display modes

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 500 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.

HDO4404 4 12 bit 400 MHz 4 GSa/s 250 Mpts (500M opt) 50,000 wfms/s
HDO4804 4 12 bit 800 MHz 4 GSa/s 250 Mpts (500M opt) 50,000 wfms/s


An oscilloscope is an important tool for making power supply measurements. With up to 12-bit vertical resolution, the HDO4000 series makes it easy for you to perform ripple measurement and quality test.

This series digital oscilloscope provides a minimum vertical scale of 100 V/div, 18 Vrms low noise floor, together with 12-bit high resolution to capture low-power small signals effectively.

It sees intricate signal details by providing up to 4 GSa/s sample rate, 12-bit vertical resolution as well as higher DC gain accuracy.

The testing for the third generation of semiconductor materials represented by gallium nitride (GaN) usually has higher requirements for reduced quantization error of T&M equipment. The 12-bit high resolution and improved DC gain accuracy make it a perfect choice for semiconductor testing.
