The bandwidth of an oscilloscope is:
- A directly related to gain compression
- B indirectly related to screen persistence
- C a function of the time-base accuracy
- D the highest frequency signal the scope can display
Correct answer: D — the highest frequency signal the scope can display. From the official ISED question bank, verified word for word.
Why
An oscilloscope's bandwidth defines the highest frequency signal it can accurately display without losing detail, much like how a camera lens has a limit on how fast-moving objects it can capture clearly. The full explanation — and one for every question — is in Pro.
