When the Invert LOGIC {Invert Output Signal} check box is checked, the output is at
a logic low when the action is occurring.

Kinetics Mode
Introduction
“Kinetics” refers to a special readout
mode in which a portion of the CCD is
illuminated while the rest of the active
area is used to store a series of frames. At
the end of the exposure-shift sequence, the
entire CCD is readout to give a series of
subframes (kinetic frames) separated in
time. In order to support this special mode
of operation, it is essential that the camera
architecture be made flexible with special
access to underlying CCD control
functions Aided by the back illumination
technology for high QE and multiplication
gain for sub-electron read noise, the
kinetics mode provides the powerful
combination of speed and sensitivity.
