  Test beam data collected in October 2004 at CERN PS to validate the AMS02
Ecal Intermediate Board (EIB) are analyzed. After describing the experimental
setup and the event samples, results concerning noise measurement, trigger
efficiency and threshold accuracy are presented. They demonstrate that the EIB
fulfils the physics requirements. Therefore the analog part of the trigger is
validated, and hardware choices are also made towards the final device.
