Example for single cursor accuracy for 70 mV signal, 10 mV/div, 0 offset:
Accuracy = ± [1.25% (80 mV) + (1.25% (0) + 2% (80 mV) + 1 mV ) + (0.4%/2) (80 mV)] =

1. Denotes warranted specifications, all others are typical. Specifications are valid after a 30 minute warm-up period and ±10 °C from
firmware calibration temperature.
2. Rise time figures are calculated from t r = 0.35/bandwidth.
3. Magnification is used below 5 mV/div range. Below 5 mV/div, full scale is defined as 40 mV. Full scale is defined as the major
attenuator setting above an intermediate setting. (Major settings 50 Ω: 10 mV, 20 mV, 50 mV, 100 mV, 200 mV, 500 mV, 1 V, 1 MΩ: all
of the above plus 2 V).
4. Vertical resolution for 8 bits = 0.4% of full scale, for 12 bits = 0.024% of full scale.
5. The dc gain accuracy decreases 0.08% of full scale per degree C from the calibration temperature.
