Trigger output
In trigger output mode, terminal IO-0 becomes an actively driven digital output. CEBO-
STICK supports two different modes to generate Trigger Output signals: alternating and
pulse output mode.
Alternating mode
In alternating mode, every acquisition of a frame toggles the level of the signal output on
IO-0. Consequently, the resulting signal is a square wave with 50% duty cycle and half
the frequency of the data acquisition frame rate.
Pulse mode
In pulse mode, every acquisition of a frame trips a short positive pulse of some 100ns
on terminal IO-0. In this mode, trigger signal rate equals the data acquisition frame rate,
but duty cycle depends on frame rate and will be less than 50%.
