ADC Bits vs. Effective Number of Bits
The number of analog-to-digital converter (ADC) bits in an oscilloscope is one of the most widely known specifications. Consequently, many engineers rely on this as the sole specification that determines an oscilloscope’s quality. However, the importance of ADC bits is often exaggerated while other critical indications of signal integrity get pushed to the background.
