Scope Trigger Generators are Synchronizers
Oscilloscope trigger generators are high-performance synchronizers. For lower-speed 'scopes, a delay is placed in the clock path between the first and second of the D flops in the diagram. This gives the first flop output time to settle to a valid logic state within the setup time needed by the second flop so that when the delayed clock comes along, the second flop avoids metastability. The delay time is chosen from the exponential equation to reduce the probability of excessive delay (the metastable state) in achieving a valid output state to an acceptably low value.

Faster scopes use hysteretic RS flops, but that is a longer story ...
