File Format
You can chose between ‘SPC Data’ and ‘SPC Setup’. The selection refers to different file
types. With ‘SPC Data’, .sdt files are loaded. These files contain both measurement data and
system parameters. Thus the load operation restores the complete system state as it was in the
moment when the file was saved.
If you chose ‘SPC Setup’, .set files are loaded. These files contain the system parameters only.
The load operation sets the system parameters, but the actual measurement data are not influ-
enced.
Note: Measurements in the ‘FIFO’ (time tag) mode deliver an .spc file that contains the micro
time, the macro time, and the detector channel for each individual photon. These files are
loaded by using the ‘Convert’ routines, see [2].
File Name / Select File
The file to be loaded can is selected in ‘File Name’ field. ‘Select File’ opens a dialog box that
displays the available files. These are ‘.sdt’ files or ‘.set’ files depending on the selected file
format. A history of previously loaded files is available by clicking on the
button.
File Info
The file info window displays information about the file selected. The first three lines of the
file info are inserted automatically when a file is saved. The last three items can be typed in by
the operator, see ‘Saving Setup and Measurement Data’.
