BLOOMING BY CLOCKING

Anti-blooming can be activated or inhibited (see 2.5.3) :

anti-blooming OFF : this position is recommended if anti-blooming is not required for the application.

anti-blooming ON : anti-blooming operation reduces the pixel saturation charge. As a consequence, camera

gain must be set to 1.30x (see 2.5.3) minimum in order to reach the camera saturation level (4095 adu)

TRIG_ITC

I

Timing control :
TRIG_ITC is either an external trigger or “ integration time control ”
depending on the timing mode configurated by RS232 (see after)
operation with external trigger :
TRIG_ITC = TRIG
operation with “ integration time control ” :
TRIG_ITC = ITC
TRIG_ITC is synchronized by the camera line clock (jitter : 200 µs)

FEN

Frame enable :
- FEN = 0 : frame data valid : active lines
- FEN = 1 : frame data not valid

SHUTTER

O

shutter open/close :
- during integration : shutter = 1
- during readout : shutter = 0
delay between the falling edge of shutter and the start of readout :
- 4 positions : 1ms, 5ms, 10ms, 20ms.
