5.5.1. Settings
This opens the submenu shown in Fig. 136. The usercontrolled factors in the analysis are defined in these dialogs, and the analysis results can be captured in the analysis report discussed in Chapter 7.
NOTE
Version 7 analysis settings (
.SDF
) files are not compatible with earlier versions of
GammaVision.
5.5.1.1. Sample Type...
Fig. 136. Settings Submenu.
This opens the multi-tab Sample Type Settings dialog discussed in the following sections. The fields on this set of screens define a complete set of
GammaVision analysis settings. Once defined, they can be saved to a Sample Description (
.SDF
) file. This .
SDF
file can then be used in
.JOB
files, in the QA analysis, as the acquisition preset default in Ask on Start, as the current defaults, and in other places within GammaVision.
To create an
.SDF
file, complete all screens of the dialog, then return to the Sample tab. Click the Save As... button in the upper right of the dialog; this will open a standard file-save dialog.
Enter the path (if necessary) and new filename, then click OK to return to the Sample tab. Click again on OK to close the Sample Type Settings dialog.
NOTE
Although this dialog has multiple tabs, any changes to the current set of “working” parameters for the selected Detector will not take effect until you click OK. To retain the current working parameters, click on Cancel.
Sample Tab
Sample settings (Fig. 137) are those whose values are generally different for each sample type.
When an
.SDF
file is recalled, the date of Creation and last date the file was updated (Edition) are displayed. Whenever the file is changed, the edition date is updated.
The Description is used to identify the sample-type file, and can be 64 characters long.
Clicking on the Presets button opens a Presets dialog corresponding to the available presets for this MCB, as discussed in Acquire/MCB Properties....(Remember that these default presets can be used automatically if the appropriate Ask on Start box in checked under Acquire/
Acquisition Settings...; see Section 5.2.1 for more information.)

783620H / 1013 5. MENU COMMANDS
Fig. 137. Sample Tab.
The Calibration data to be saved with the spectrum or used for online analysis can be the currently loaded Internal (working) calibration or a calibration stored on disk. The working calibration is the calibration just created with the Calibrate menu commands (see Section 5.3.1) or the calibration most recently recalled from disk. When the
.SPC
file for this spectrum is saved to disk, the current calibration will be saved with it for later analysis. The interactive analysis
(performed with Analyze/Interactive in viewed area), uses the internal calibration.
Note that each Detector and buffer can have separate calibrations.
26
This is useful if different types of calibrations (e.g., point source and Marinelli beaker calibrations) are used for different types of samples.
26
Note to previous GammaVision users: The Detectors are calibrated directly, therefore it is no longer necessary to move the spectrum to the buffer in order to do a calibration. If the spectrum is moved to the buffer and the buffer is used for calibration, then the calibration is not associated with the Detector unless the calibration is moved to the Detector by using the Calibrate/Save Calibration... and Calibrate/Recall Calibration... commands.
