• State
A trigger is activated in any of the following cases.
• When the state condition is met or ceases to be met.
• The DL9000 checks the state condition at the rising or falling edge of the specified
signal (clock signal) and normalizes the result (high if the state condition is met or
low if not). A trigger is activated when the normalized condition changes.
