1 V/div – 10 V/div ≤200 V ≤2.5 ≤0.2
Common Mode Rejection Ratio (CMRR) 100:1 at 60 Hz, reducing to 20:1 at 50 MHz, with equal Volts/Div and Coupling settings
on each channel.
1
Net Offset = Offset – (Position × Volts/Div). Net Offset is the voltage level at the center of the A-D 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.
3
The values given are the maximum absolute difference between the value at the end of a specified time interval after the
mid-level crossing of the step, and the value one second after the mid-level crossing of the step, expressed as a
percentage of the step amplitude.
