Sure but the question remains--why? If I know that the signal amplitude is within range for the task and my cables are short then why would I want to stick an additional 50 ohm feedthru in the signal path?
To avoid reflections from the unterminated input of the scope.
Try connecting a fast rise generator (10MHz square wave would be fine)
to the scope through an unterminated cable, then add a terminator.
You'll see a huge difference.
