High-resolution oscilloscope can effectively improve the accuracy of signal measurement. The quantization level of the traditional 8-bit resolution oscilloscope is 256, while the quantization level of the 12-bit resolution is 4096, which means that the minimum signal amplitude that can be measured under 12-bit is 1/4096V, while that of 8-bit is only 1/256 V.. The resolution of 12-bit can reach 16 times that of the traditional 8-bit, which improves the measurement accuracy of the signal by an order of magnitude.

High-resolution oscilloscopes require extremely high noise floor, otherwise small signals will be easily submerged in noise. The noise floor of SDS6000L is only 153 μVrms, and its DC gain accuracy can reach 0.5%, which enables 12-bit ADC to give full play to its performance and enables users to observe more waveform details.
