Offset = Offset - (Position x Volts/Div). Net Offset is the nominal voltage level at the oscilloscope input
that corresponds to the center of the A-D converter dynamic range. Offset Accuracy is the accuracy of this
voltage level
2The limits given are for the ambient temperature range of 0C to +30C. Reduce the upper bandwidth
frequencies by 2.5 MHz for each C above +30C
