measurement accuracy
(average sampling mode)
When vertical shift is zero and N ≥16 :
± (4% x reading + 0.1 div + 1mV) and 5mV/div is selected;
± (3% x reading + 0.1 div + 1mV) and 10mV/div~50V/div is selected;
When vertical shift is not zero and N ≥16 :
± (3% x (reading + vertical shift reading) + (1% x vertical shift reading)) + 0.2
div). Set from 5mV/div to 200mV/div plus 2mV;
Setup value > 200mV/div to 50V/div plus 50mV.
Under identical setup and environmental conditions, the voltage difference
(
Ƹ
V) between two points of the waveform after the average of ≥16
waveforms acquired waveforms is taken : ± (3% x reading + 0.05 div).
