The Compact Muon Solenoid (CMS) detector is currently advancing with its Phase-2 upgrade, in preparation for operation in the High-Luminosity LHC. Once upgraded, the CMS experiment will incorporate a completely new tracker, including an Inner Tracker based on pixellated silicon sensors. The pixel chips for the Inner Tracker are developed by the RD53 collaboration.

In this paper, we present the latest calibration test results for the RD53B-CMS (CROC_v1) chips with sensors. The performance of the chip is studied in order to optimize the calibration procedure for the real experiment. Using the latest DAQ system features, test results to optimize the hit detection threshold and signal gain using the chip's internal calibration circuit and a radioactive X-ray source, are presented.
