The CMS Collaboration is developing silicon strip modules for the second phase of the CMS tracker upgrade. This upgrade will enable the CMS experiment to utilize the high luminosity provided by the future HL-LHC. The modules' Service Hybrids are responsible for the sensor bias voltage and low voltage distribution on the module and the data transmission via optical links to the back-end electronics. For the first time, final versions of the required ASICs were assembled and tested on Service Hybrid prototypes with materials and geometries as foreseen in the detector. The measurements were performed with setups similar to the foreseen production test system. The gained experience is crucial for the design validation and in taking the final choices in the design process before series production.
