The Observer XT - Up and running quickly

Last updated: Jul 25, 2026

Up and running quickly

Working with The Observer XT consists of three main steps. These three steps are visible in the main window of The Observer XT that opens once you have created a project (page 6). In step 1 you create all the necessary settings for your observations (page 6). In step 2 you collect your data (page 13). And in step 3 you analyze your data (page 17). This Quick Start Guide guides you through these main steps. Only the most basic features of The Observer XT are addressed. Inevitably, some features that may be vital to your application are not discussed. You find additional information in The Observer XT Help. Press F1 in The Observer XT to open it.
