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