000003230 520__ $$aThe present thesis focuses on the calibration, optimization and precision characterization of the PXD II modules, which are scheduled to be installed in the PXD detector during 2022. Each PXD module must be tested for full functionality after fabrication. In addition, operation parameters have to be tuned individually to achieve good detector efficiency. An optimization process on the modules is particularly important to ensure the homogeneity of the pixel response. To understand in more detail the properties of the PXD module, two characteristic quantities, the transconductance gm and the internal amplification gq are investigated pixel by pixel in the PXD module. Furthermore the influence on the readout current of the digitization process is investigated.
