Characteristics Description
±3% for Sample or Average acquisition mode, 5 V/div to 10 mV/div DC Gain Accuracy
±4% for Sample or Average acquisition mode, 5 mV/div and 2 mV/div
Measurement Type Accuracy
Average of ≥ 16 waveforms with
vertical position at zero
±(3% × r 0.1 div + 1 mV) when 10 mV/div or
greater is selected

Add 2 mV for settings from 2 mV/div to 200 mV/div
Add 50 mV for settings from > 200 mV/div to 5 V/div

The oscilloscope reverts to Sample mode when the SEC/DIV (horizontal scale) is set from 2.5 μ s/div to 5 ns/div on 100 MHz models, or from 2.5 μ s/div to
2.5 ns/div on a TPS2024B model. Sample mode can capture 12 ns glitches.
