Princeton Instruments does not encourage users to change these parameter settings. For

contacting the factory for guidance before customizing the chip definition.
In WinX, if Custom Chip has
been installed, selecting Show
Custom Chip check box on
the Controller/Camera tab
adds the Custom Chip tab to
the Hardware Setup dialog.
The Custom Chip parameters
are shown in Figure 46. The
default values conform to the
physical layout of the CCD
array and are optimum for most
measurements.
In LightField, the Custom
Sensor pane (Figure 47) is
accessed by opening the Sensor
expander and clicking on the
Custom Sensor button.
By changing the values in the
Active fields, you can increase
image acquisition speed by
reducing the size of the active
area in the definition. The result
will be faster but lower
resolution data acquisition.
Operating in this mode would
ordinarily require that the chip be
masked so that only the reduced
active area is exposed. This will
prevent unwanted charge from
spilling into the active area or
being transferred to the shift
register.
By default, if there are no Pre-
Dummy rows, the serial register
will be cleared before rows are
shifted. If the Skip Serial

Register Clean box is selected in WinX when there are no Pre-Dummy rows, the register
cleanout will be skipped and the chip readout will be faster.
Note: In LightField, the Clean Serial Register function only appears in the Sensor
Cleaning pane when the Inactive Area Top Margin is 0 rows. Deselect the check box
to deactivate the serial register cleaning.
