Abstract

We present a digital fully configurable architecture that performs the function of signal generation for emulation of radiation detectors and front-end. A novel algorithm is proposed that modulates the amplitude of the synthesized pulses generated by the system according to the source energy spectrum given as an input. Furthermore the same architecture is used to emulate the statistic time interval of emission. The system has been prototyped and is being fully tested on a Xilinx Virtex-5 FPGA device.
