In the context of the Phase-2 Upgrade of the CMS experiment, the complete CMS tracker will be replaced. The new CMS Outer Tracker will consist of two types of silicon sensor modules (PS and 2S modules). These modules are built and tested for their full functionality at different assembly centers. The ETP is one of the assembly centers for 2S modules. A dedicated test station for the electrical characterization of 2S modules has been designed and built at ETP. Using infrared LEDs it is possible to generate charge in the silicon sensors and test every module channel. This talk will present the test station developed at ETP and summarize the functional test results of the newest 2S module prototypes.
