Signal definitions
T
erm Definition
User Trigger Trigger signal applied by the user (hardware trigger,
software trigger)
Logic Trigger Trigger signal seen by the camera internal logic (not
visible to the user)
Tpd Propagation delay between the User Trigger and the Logic
Trigger
Exposure ... is high when the camera image sensor is integrating
light.
Readou
t
... is high when the camera image sensor is reading out
data.
Trigger Latency Time delay between the User Trigger and the start of
Exposure
Trigger Jitter Error in the Trigger Latency Time
Trigger Ready ... indicates to the user that the camera will accept the
next trigger.
Registered Exposure Time ... is the Exposure Time value currently stored in the
camera memory.
Exposure Start Delay ... is the Registered Exposure Time subtracted from the
Readout time and indicates when the next Exposure cycle
can begin such that the Exposure will end after the current
Readout.
Interline Time ... is the time between sensor row readout cycles.
Imaging ... is high when the camera image sensor is either
exposing and/or reading out data.
Idle ... is high if the camera image sensor is not exposing
and/or reading out data.
