If oscilloscopes are one of the main tools that analyze electrical signals as they give a full representation of the signal amplitude variation over time why most scopes I’ve seen (if not all) don’t have THD specification on their data sheet? 😕
Remember, a scope gives a visual representation. Your eyes are not particularly sensitive to HD- it takes several percent before it becomes clearly visible.
Now I know there is no need to exert effort looking for THD spec on any scope data sheet. Thanks Stuart.

So what scope brand & model is the data sheet? If linearity specification is more meaningful how come popular brands like Agilent, LeCroy, & Tektronix (mentioned in alphabetical order) don't specify them on their data sheet?

This spec is extracted from the TEK 2445 manual:

But I've seen this kind of spec (maybe with a slightly different formulation) on other instruments and manufacturers.
