Coupling settings on each channel.
1
Net Offset = Offset - (Position × Volts/Div). Net Offset is the voltage level at the center of the AĆD converter dynamic range. Offset
Accuracy is the accuracy of this voltage level.
2
The samples must be acquired under the same setup and ambient conditions.

The values given are the maximum absolute difference between the value at the end of a specified time interval after the midĆlevel
crossing of the step, and the value one second after the midĆlevel crossing of the step, expressed as a percentage of the step
amplitude.
