Figure 4.3: Data Operations dialog box

This dialog allows to edit the data settings. Mark the checkbox „Save at Halt" to store a spectrum-
and a configuration file at the end of a measurement. The filename can be entered. If the
checkbox auto incr. is checked, a 3-digit number is appended to the filename that is
automatically incremented with each saving. The format of the data file can be ASCII (extension
.ASC), binary (.DAT), or GANAAS (.SPE). The buttons Save, Load, and Erase perform the
respective operation. With Add and Sub a spectrum can be added or subtracted from the present
data. The Checkbox calibr. is checked if a calibration is used and the data is then adjusted
according to the calibration. The Smooth button performs an n-point smoothing of the data. The
number of points to average can be set with the Pts edit field between 3 and 21.

With the combo box „Range" the length of the spectrum can be chosen. If the checkbox
„ROIpreset" is marked, the measurement will be stopped after acquiring more events than
specified in the corresponding edit field. The events are counted only if they are in the „ROI" limits,
i.e. >= the lower limit and < the upper limit. Another possibility is to acquire data for a given
realtime via the „RealTime Preset" or livetime via the „Livetime Preset". OK takes all settings.
Cancel cancels all changes. Pressing Save Sett. writes all settings in the file WEBCAA.CFG or
the name entered in the Setup name edit field with "A.CFG" appended.
