Performance-Enhanced Versus Standard Models
In the fall of 2000, keysight started shipping performance-enhanced models of the
90000 A-Series oscilloscope. This service guide covers both the standard and
performance-enhanced versions. Any differences between the two versions are
noted.
To tell whether the oscilloscope you have is a standard one or a

handles.
