This topic describes the behavior of the CIC when it is configured to generate one sequence of 4 cycles, each with different timings settings.

Camera model parameters

● CameraControlMethod=RG;
● ExposeReadoutOverlap=TRUE;
● ExposureRecoveryTime set to r time interval in the drawing
● CycleMinimumPeriod set to c time interval in the drawing

Cycle timing parameters

CycleTimingCount=4

CycleTimingSelector 0 1 2 3
ExposureTime e1 e2 e3 e4
StrobeDelay 0 0 0 0
StrobeDuration e1 e2 e3 e4
1. In this example, the Strobe signal is identical to the Camera Trigger signal
2. Exposure times (e1, e2, e3, e4) are all different, starting with the smallest and ending with the largest.

Cycle control parameters

● CycleTriggerSource=Immediate;

Sequence Control parameters

● StartOfSequenceTriggerSource≠Immediate;
● EndOfSequenceTriggerSource=SequenceLength;
● SequenceLength=4;

Description

Optimal sequence of 4 cycles with different timing settings

The sequence starts with the Start Sequence Trigger event (#1 in the drawing)and stops automatically after 4 cycles.

The next sequence may only start after the completion of the first sequence.

The four cycles of the sequence are overlapped with the minimum time interval between cycles according to Camera Cycle Concatenation Rules.

The first three cycles are "Readout Limited"; the fourth cycle is "Exposure Limited".

After having executed 4 cycles, the CIC controller falls back to the first timing definition.

The sequence terminates slightly (e1 time) before the end of the fourth readout allowing the next sequence to begin with the optimal timing.
