Influence of electromagnetic interference on the analog part of hybrid pixel detectors Electro-magnetic interference influences proper function of pixel detector Motivation is to gain more knowledge about potential sources of internal and external electro-magnetic interference and their level of influence Experiences are planed to be used for development of new more immune version of FITPix like detector interfaces Set-up of Timepix detector and FITPix interface under several tests Measurement and analysis of internal and external sources of interference Bias voltage noise immunity Power supply network noise immunity Influence of power supply voltage shift Close electro-magnetic field immunity Distant electro-magnetic field immunity Read-out chip erradiated electro-magnetic field Influence of Timepix measurement clock frequency
