Triggered Mode Without Overlap - XIMEA xiQ series Technical Manual

4.3.2.3.

Triggered mode without overlap

This mode gives lower FPS compared to Free-Run mode and lower FPS than Exposure Overlapped with Data Readout mode.
Sensor timing in Exposure Overlapped with Data Readout Mode
figure 4-2, acquisition mode – triggered without overlap
In this mode the timing depends on sum of:
• Input transition time (t
o Digital Input Delay - time for changing internal circuit to active state. It is constant for each camera model.
o Input Debouncing Time - time for stabilizing uneven input signals (e.g. from mechanical switches). This time can be can
be set using xiAPI with parameters XI_PRM_DEBOUNCE_EN and XI_PRM_DEBOUNCE_T0 on some cameras. Default 0.
• Exposure time (see ET above).
• Data Readout time (see t

Description:
DownS = Current camera DownSampling (XI_PRM_DOWNSAMPLING)
t = Trigger (Digital Input) to Strobe (Digital Output) (on some models is listed: Off->On change / On->Off change)
eio
t = Strobe (Sensor) to Digital Output (on some models is listed: Off->On change / On->Off change)
exp
t = Start of exposition to Exposure Active Digital Output
expo
LC = Current Line Count (XI_PRM_ HEIGHT)
BW = Bandwidth Factor for maximum bandwidth this is 1 when the bandwidth will be lower BWF will rise (TBD)
t = Current Exposure Time set (XI_PRM_EXPOSURE)
