Table 1: Signal acquisition system characteristics (cont.)
This is the accuracy of the nominal voltage level represented by the code at the vendor of the A-D
converter's dynamic range.
Volts/Div Setting
Position Accuracy
2 mV/div to 200 mV/div ±(1% of |selected value| + 0.1 div + 5 mV) within the
range ±1.8 V
√ Vertical Position
Accuracy
> 200 mV/div to 5 V/div ±(1% of |selected value| + 0.1 div + 125 mV) within the
range ±45 V
With the same signal applied to each channel, CMRR is the ratio of the acquired signal amplitude to the
amplitude of the MATH difference waveform, either (Channel 1 - Channel 2), (Channel 2 - Channel 1),
(Channel 3 - Channel 4) or (Channel 4 - Channel 3)

Section 4.11.1 of IEEE std. 1057. It is the ratio of the level of a signal input into one channel to that of
the same signal present in another channel due to stray coupling.
