Frequently Asked Questions:
Question: 8 bit, 12 bit - which vertical resolution do I need for my oscilloscope? Or: Why an "HD scope"?
Answer: The vertical resolution of the oscilloscope is the resolution of the A/D converter in the oscilloscope. During the A/D conversion of a signal, an analog, value- and time-continuous signal becomes a value- and time-discrete signal. The infinite number of voltage values thus becomes a limited number of values that can be binary coded during digitization. The determining variable here is the bit width of the A/D converter. With a 16-bit converter, for example, 65,536 values can be represented (4096 with 12 bit, 256 with 8 bit). Strictly speaking, the digitized signal is always only an approximation of the original signal. The higher the resolution and rate, the better this approximation, but the higher the amount of data produced. However, the A/D converter is still a price-sensitive component.
For classic DSOs (digital storage oscilloscopes), a resolution of 8 bit is still the standard at the present time. For many applications this is perfectly sufficient. But the modern converter technology allows of course also higher resolutions like eg. with the Rigol DHO series. And this gradually also at more and more favorable prices (we are talking here about "real" 12-bit conversion, not about "extended" modes with reduced bandwidth generated by mathematical filter algorithms etc.). There are applications where these higher resolutions are required - for example, when capturing and analyzing high dynamic range signals, when capturing small signals in the context of large signal amplitudes. Small details become more visible and sharper signals are possible.
