Uniformity II Stand-Alone Test Control Panel
Figure 5-21 shows the test panel of the subVi, which may be run as an independent test.
When run as an independent test, the program asks for the location of the test constants file,
so that the same limits can be used in the stand-alone as in the complete test. In addition to
performing the same basic test as the version in the complete test, options are provided to
show plots of the data (see Figures 5-19 and 5-20). The panel also provides:
• Individual array’s of RGB dust locations and bad pixel flags.
• Additional statistics on the uncorrected dark response.
If the Force New Cal option is selected or, a successful calibration has not been performed
since the slide scanner was last powered up, a new calibration is performed and new data
analyzed. Otherwise, the data tested will be from the last valid calibration.
Note the Flatten Curves slider on the Display Uniformity On panel shown in Figure 5-19
(top left). If this option is selected, and the run button (arrow at top left of panel) of the display
panel is selected by a mouse click, the display is updated to show the original RGB curves
normalized to their individual curve fits. This option provides a means of highlighting only the
higher frequency variations in the uncorrected light response.
