The primary use case is for testing IT files. We are testing files for memory read or write (or other scenarios), but mostly it is on the platform, test package, of both.
The bandwidth is up to 10 gigabytes per second for the oscilloscope because we are testing high speed signals.
I'm not a frequent user. Sometimes we use the oscilloscope for measurement. It depends on product and what testing that we are trying to do.
I have used oscilloscopes since I was a Bachelor's student, where we used different types of oscilloscopes.
