The purpose of a digital oscilloscope is to display an electrical signal over time.
A key component of a digital oscilloscope is the Analog-to-Digital Converter (ADC), which converts the input analog signal into a digital one.
The number of bits in the ADC determines the quantization levels of the oscilloscope’s input analog signal — that is, how finely and accurately the analog signal will be converted into a digital format.
A higher bit count in the ADC leads to greater resolution of the digital signal on the vertical axis, resulting in more accurate measurements and improved detail discernibility in the oscilloscope.
The new Keysight HD3 oscilloscope features a 14-bit ADC, paired with a very low-noise front-end. This combination results in high signal measurement quality (Signal Integrity), as the effect of noise on the oscilloscope’s input signal is reduced and the vertical resolution of the measurement is increased.
Below is a comparison of the same signal measured with an 8-bit oscilloscope and a 14-bit oscilloscope:
