== Open data and save the processing document ==
This section is intended as an introduction to the analysis of XPS data. Simple examples are chosen to illustrate the procedures. All actions performed with Avantage (version 5.498) during an analysis of a sample are shown.  
 
Locate the .VGX file in the experiment data tree. Either open the experiment by selecting 'Open Experiment' in Avantage, or double click on the .VGX file. You will see something like this:
 
[[File:XPS-basics00.jpg|700px]]
 
It is a very good idea to save the processing document as you analyze the data (Avantage may crash some times) - to do so, select 'Save Processing Document' and you analysis will be saved as a .VGD file.


== Survey spectrum and depth profile ==
In case you want to follow along with your own analysis, you can download the data from [[Media:20150518_ZnO_CuZn_ZnO.doc| here (this file is a .zip file that has been renamed to .doc in order to be uploaded to LabAdviser, so download and rename to .zip and extract the files)]]


As seen in the screendump below, the experiment consists of a survey spectrum and a series of high resolution spectra
