The Institute of High Energy Physics (HEPHY), which is a part of the Austrian Academy of Sciences (OAW), is participating in the Belle 2 experiment. A major objective is to develop and construct the Silicon Vertex Detector (SVD) which is an inner tracking detector of Belle II. Belle II is a highly advanced B-physics experiment and therefore requires an ingenious SVD detector which is unique in his construction and application. Thus ongoing tests for functionality and quality assurance have to be conducted. These tests comprise in-house small-scale ladder checks up to high energy particle beam tests. This master thesis is about data analysis from single ladders to fully configured telescope tests and the developed test environment. Thus the thesis contains signal analysis and first tracking tests with a fully assembled L5 ladder in the final SVD configuration at CERN-SPS as well as the development of a Ladder-Test-System (LTS). The LTS aimed at testing the functionality of the fully assembled ladder with a 90Sr source. Moreover, an open CO2 cooling device (ACBC) was developed for cooling-tests after mounting the ladders on the final setup.
