A Navigation Reference of
Lock to Trigger
rescales divisions around the trigger point. The trigger event remains in place as Time/div changes, while other events
move in reference to the trigger. If the trigger is currently placed at time zero, this will appear to behave the same as Centered, but the difference will be apparent
if you have used Delay to shift the trigger position.
Same 2 ms/div Timebase with Timebase Reference set to Lock to Trigger starts the same as when Centered.
Now, when the Timebase is changed to 1 ms/div, the trigger event remains at its current position, but the rest of the
trace shifts to the right as time "expands." The values associated with each horizontal grid division are different than
when centered, although Time/div is still 1 ms/div.
