60 MI.61xx Manual
External TTL trigger Trigger modes and appendant registers
Positive and negative TTL trigger
This mode is for detecting the rising and falling edges of an ex-
ternal TTL signal. The board will trigger on the first rising or falling
edge that is detected after starting the board. The next triggere-
vent will then be detected, if the actual recording/replay has fi-
nished and the board is armed and waiting for a trigger again.
