Software Settings
Princeton Instruments does not encourage users to change these parameter settings. For
most applications, the default settings will give the best results. We strongly advise
contacting the factory for guidance before customizing the chip definition.
In WinX, i, f 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 40. 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 41) 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
when there are no Pre-Dummy rows, the register cleanout will be skipped and the chip
readout will be faster. This feature is not available for PVCAM-supported cameras.
Note: In LightField, the Clean Serial Register function only appears in the Sensor
Cleaning pane when the Inactive Area Top Margin has been set to 0 rows. Deselect the
check box to deactivate the serial register cleaning.
