There exist different ways to extract the BPM noise, as the "three-BPM" correlation method or the model-independent principal components analysis (PCA). Both methods will shortly be reviewed. Based on a PCA, the resolution of the PETRA III Libera Brilliance based BPM system was measured. The results will be presented together with first measurements in view of an updated BPM system for the future PETRA IV project at DESY.
