5.13 WinX Experiment Setup
This section provides information about configuring an experiment using the WinX
application software.
5.13.1 Main Tab
Within WinX, experiment setup parameters are typically configured on the
Experiment
Setup —> Main
tab. See Figure 5-20 .
Figure 5-20: Typical Experiment Setup Dialog: Main Tab
These parameters configure such things as the number of separate frames (denoted as
images or spectra) that will be acquired, how much of the CCD will be used to acquired
data, the intensifier gain, and the intensifier mode. Each of the Main parameters are
described briefly below.
• Number of Images/Spectra and Accumulations
This is the number of sequential frames the software will collect and store in a single file.
Each frame will be digitized and stored, but all of the frames will be in a single file. A
frame may contain data from more than one region of interest as defined via the
ROI
Setup tab.
If the Accumulations > 1, each stored frame will contain summed data sets from
two or more exposures. The number of separate frames stored will the same as it
would be for Accumulations =1, but the total number of exposures required would
be the product of the
Number of Images/Spectra
parameter times the
Accumulations value.
• CCD Readout
This parameter determines whether the entire CCD array will be used to acquire a
frame or if only a rectangular portion (or portions) of the array will be used. When
Use Region of Interest
is selected, data will be collected from the region(s) as
defined on the ROI Setup tab. The full chip size or the sum of the active region(s)
as defined on the ROI tab is displayed.
