A silicon- and a CdTe-sensor were bump bonded onto the MPEC pixel readout chip and could be successfully operated. A new USB based readout system was used for data acquisition. Measurements of the performance on the latest MPEC chip and imaging characterization of the sensors are presented.5 pages, 10 figures, submitted to Nucl. Inst. Meth.
