N2  - Between 2019 and 2022, the LHCb experiment has undergone a major upgrade. It enables the detector to be operated at an increased luminosity and to be read out at 40 MHz corresponding to the proton bunch crossing rate at the LHC. In the course of the upgrade, the tracking stations downstream of the magnet have been replaced by a tracker made of scintillating fibres. With a fibre diameter of 250 ?m, silicon photomultiplier readout and custom front-end electronics, it is well suited for the conditions of the next data taking period.
The front-end electronics of the Scintillating Fibre (SciFi) Tracker follow a modular design and have been optimised for the detector readout at 40 MHz. Before being installed in the upgraded LHCb experiment, every component is thoroughly tested as part of a detailed commissioning procedure. This thesis describes the process of the commissioning and presents the results of a large fraction of the detector. Along with further performance studies, it could be shown that even on large scales the SciFi front-end electronics meets very high quality standards.
