Then initiate the import of the sample spectra by right-clicking the Measurements node under the project and the select Import spectrum files from the pop‑up menu.
Spectrum file importer appears now.
Click Add files button, and select 10 sample Accuspec spectra with “A” ending in their file name, as can be seen in the picture.
Do not forget to check the settings under the Main settings tab.
Here you should specify the Dual LFC spectrum evaluation mode first, as these measurements are created using an LFC module, allowing compensation for count losses due to varying or high count rate situations.
At the Measurement setup combo box, you should select HyperLab's sample measurement setup. This is an important setting, because nonlinearity analysis will belong to a specific setup, and its input measurements should also have reference to the same setup.
If the sample setup can not be found in the list, create it by clicking on the New entry button beside the combo box.
Now you can enter the data for this sample setup. When you are ready, click OK.
The spectrum import form will appear again.
You should check the Calibrations tab now, where the source of FWHM and energy calibrations should be set to Spectrum files' own calibration values.
Click Load files button in order to initiate the spectrum loading.
All selected spectrum files will be loaded now, and the importer will provide basic information on the loading process.
Click Close to finish loading.
The database browser now displays the imported spectra. Now we will complete their missing sample settings.
The sample is important presently only for calibration measurements, serving as input for later nonlinearity, efficiency and resolution analyses. These analyses will identify gamma lines by using isotope information, which is in turn supplied by the user, during the sample definition.

To define a source, click the measurement and select its “Measurement properties” task. The measurement's property editor window appears now.
Please check if its Source field is set. If there is no reference to an existing source, or the Measurement object type field does not set to Source, then changes have to be made.
