A universal diagnostic platform is described which incorporates several measurement modules for testing a device under test. In order to increase the erasing efficiency, provision is made such that the reflector is arranged andor designed such that it reflects erasing radiation, which is reflected by the storage phosphor layer, in the direction of the storage phosphor layer, and the radiation source is disposed on a base, the base being disposed closer to the holding plane than at least part of the reflector. Related systems, apparatus, and methods are also described. The controller controls the communication with the device. A power supply arrangement is also located within the channel.
