How high is the measurement accuracy of the ZDS2022 oscilloscope?

All signals are processed by the conditioning circuit before being input to the ADC. For small signals, the input amplifier in the conditioning circuit will amplify the small signal to ensure that the amplitude of the amplified signal best matches the input voltage range of the ADC.

The measurement accuracy of the oscilloscope is not only related to the vertical resolution (the vertical resolution of the ZDS2022 oscilloscope is 8 bits), but also to the vertical gear. For example, at the 2mV/div gear, the full scale is 8 grids, that is, 16mV (2mV/div*8div=16mV), and the saturation overflow margin exceeds the screen by 2.24 grids, which is 4.48mV, a total of 20.48mV, which corresponds to the 0~255 range of the 8-bit ADC. The measurement accuracy at this time is.
