• Pulse State
A trigger is activated in any of the following cases.
• When the time during which the state condition is met or not met satisfies the
relationship with the specified determination time.
• The DL9000 checks and normalizes the state condition on the rising or falling edge
of the specified signal (clock source). A trigger is activated when the time during
which the normalized condition is met or not met first satisfies the relationship with
the specified time.
