Alternating Mode
In alternating mode, every acquisition of a frame toggles the level of the TRG output signal. 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 trigger event initiates a pulse of several 100ns on TRG terminal. In this mode TRG
signal rate equals the frame rate used for data acquisition, but duty cycle depends on frame rate and will be
less than 50%.
Trigger application example
To get higher frame rates or channel counts, you can use two ore more CEBO-LC devices in parallel. In
many cases, an identical acquisition rate is required for all devices. Then, "alternating mode" is the first
choice.
To setup for this scenario, connect all the TRG terminals of all devices together. Because CEBO-LC is
isolated from host ground, additionally connect the GND terminals.
Configure one device for Alternating Trigger Output mode (master) and all others for Alternating Trigger Input
mode (slaves).
