When vertical sensitivity is 2mV/div ±4% (sample or average
When vertical sensitivity is 5mV/div~5V/div ± 3% (sample or
average sampling mode)
When vertical position is zero and N≥16:
±(5%x reading+0.1div+1mV) and 2mV/div is selected;
±(3%x reading+0.1div+1mV) and 5mV/div is selected.
When vertical position is not zero and N≥16:
±(3%x(reading+vertical shift reading) +(1%xvertical shift
reading)+ 0.2div) Set from 5mV/div to 200mV/div plus 2mV;
Setup value >200mV/div to 20V/div plus 50mV.
Under identical setup and environmental conditions, the voltage
difference (rV) between two points of the waveform after the
average of ≥16 waveforms acquired waveforms is taken:
