Sumario: | The CMS Pixel phase 1 upgrade detector consists of 1184 modules with new design. An important part of the production is the module qualification and calibration, ensuring their proper functionality within the detector. This paper summarizes the qualification and calibration results of modules used in the innermost two detector layers with focus on methods using module-internal calibration signals. Extended characterizations on pixel level such as electronic noise and bump bond connectivity, optimization of operational parameters, sensor quality and thermal stress resistance were performed using a customized setup with controlled environment. It could be shown that the selected modules have on average $0.55 \mathrm{ {}^{0\!}\!/\!_{00} }\, \pm \, 0.01 \mathrm{ {}^{0\!}\!/\!_{00} }\,$ defective pixels and that all performance parameters stay within their specifications. |
