DC Measurement Accuracy,
Average Acquisition Mode
Measurement Type: Average of ≥16 waveforms with
vertical position at zero
Accuracy: ± (3% × reading + 0.1div + 1mV) when
10mV/div or greater is selected
Measurement Type: Average of ≥16 waveforms with
vertical position not at zero
Accuracy: ± [3% × (reading + vertical position) + 1% of
vertical position + 0.2div]
Add 2mV for settings from 2mV/div to 200mV/div; add
50mV for settings from 200mV/div to 5V/div
Volts Measurement Repeatability,
Average Acquisition Mode
Delta volts between any two averages of ≥16
waveforms acquired under same setup and ambient
conditions
Note: Bandwidth reduced to 6MHz when using a 1X probe.
