Sample acquisition mode,
typical
Absolute measurement of any waveform
point, and High, Low, Max, and Min
measurements
±[(1.0% ×| reading -- net offset | ) +
offset accuracy + (0.13 div ×V/div
setting) + 0.6 mV]
Delta voltage measurement between any
two points acquired under the same
setup and ambient conditions, and all
other automatic measurements
±[(1.0% ×| reading | ) + (0.26 div ×
V/div setting) + 1.2 mV]
nAverage acquisition mode
(≥16 averages)
Absolute measurement of any waveform
point, and High, Low, Max, and Min
measurements
±[(1.0% ×| reading -- net offset | ) +
offset accuracy +( 0.06 ×V/div)]
Delta voltage measurement between any
two points acquired under the same
setup and ambient conditions, and all
other automatic measurements
±[(1.0% ×| reading | ) + (0.1 div ×
V/div setting) + 0.3 mV]
Net offset is the nominal voltage that must be applied to the channel to bring the
trace to center screen. Net offset = offset -- ( position ×volts/division)and is
expressed in volts
