In the scope of the HL-LHC upgrade the new CMS Tracker will be built. The future tracker will consist of two module types: strip-strip (2S) and pixel-strip (PS) modules. In order to stress the operation of these modules a test beam at the CERN Highly-Accelerated Mixed Field Facility (CHARM) was performed. The facility provides a mixed particle spectrum, which allows to operate the modules in an environment close to realistic conditions of the future detector. The modules were irradiated with a flux of up to ∼ 10⁷/cm² · s. The data was successfully collected with a prototype of the final data acquisition chain. Technical details of the test beam operation as well as results of the studies performed during the test beam are presented.
