The definition of a high-performance oscilloscope really is all about the customer's point of view. Two scopes may have the same bandwidth, number of channels, sampling rate, operating modes, and memory length. Yet, one will be bought instead of the other because its software or triggering capability or measurement suite better matches the customer's application requirements.
