Note: Offset, position, and the constant offset term must be converted to volts by multiplying by the
appropriate volts/div term.
The basic accuracy speci
fi cation applies directly to any sample and to the following measurements: High,
Low, Max, and Min. The delta volt accuracy speci fi cation applies to subtractive calculations involving
two of these measurements.
The delta volts (difference voltage) accuracy speci
fi cation applies directly to the following measurements:
Positive Overshoot, Negative Overshoot, Pk-Pk, and Amplitude.
Volts/div setting Offset range
2 mV/div to 200 mV/div ±1 V
Vertical offset
ranges
>200 mV/div to 5 V/div ±25 V
Vertical offset
accuracy ±[0.01 × |offset - position| + DC Balance]
Note: Both the position and constant offset term must be converted to volts by multiplying by the
appropriate volts/div term.
