DC vertical offset accuracy
≤
200 mV/div: ±0.1 div ±2.0 mV ±0.5% offset value;
> 200 mV/div: ±0.1 div ±2.0 mV ±1.5% offset value
DC vertical gain accuracy
±4.0% of Full Scale
Single cursor accuracy
±{DC vertical gain ac DC vertical offset ac 0.2% full scale (~1/2 LSB)}
Example: for 50 mV signal, scope set to 10 mV/div (80 mV full scale), 5 mV offset,
accuracy = ±{4.0% (80 mV) + 0.1(10 mV) + 2.0 mV + 0.5% (5 mV) + 0.2% (80 mV)}
= ±6.385 mV
Dual cursor accuracy
±{DC vertical gain ac 0.4% full scale (~1 LSB)}
Example: for 50 mV signal, scope set to 10 mV/div (80 mV full scale), 5 mV offset,
accuracy = ±{4.0% (80 mV) + 0.4% (80 mV)} = ±3.52 mV
