Mode description :
•
Single-shot : standard image acquisition and readout cycle featuring 0.5 s (default mode)
or 1s or 4s X-ray Enable window duration
•
Special : same as above with X-ray enable window duration increased to 3.2 s
•
Reverse readout : same acquisition mode with reverse readout of the lines (from center to
top and bottom line)
•
Readout IC self test : internal self test of the amplifier readout circuits (outputs a test
image with white odd / even columns)
•
Readout IC voltage readout : an internal reference voltage is applied on the inputs of the
amplifier readout circuits (outputs a test image with a constant gray level)
•
Test modes : an internal signal source is used to simulate X-ray exposure at 5 or 30 µGy
dose level
•
Double exposure : two frames (frame A and frame B) can be acquired within an interval
of max. 2 sec ; the cycle time between two acquisitions in Double exposure mode is min.
6.5 sec.
