Default Question about Tektronix SC501 scope

The crt beam seems very feeble at these two highest writing speeds.
Very unimpressive for what I would call Tek's normal high standards.
Not in the same ballpark as my SC502 dual trace unit for instance.

Are you triggering the sweep at the higher speeds or just letting it
auto-trigger? Auto-trigger is done at a low rate and makes the sweep
very dim until it gets an actual high frequency trigger.
