Performance characteristics¹ (continued)
Vertical system: oscilloscope channels (continued)
Single-cursor accuracy
±{DC vertical gain accuracy + DC vertical offset accuracy + 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 accuracy + 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
