A high energy resolution X-ray spectrometer based on Silicon Drift Detector is described in this paper. The spectrometer consists of the SDD detector module, the analog electronics for shaping and filtering and the digital electronics for peak detection and data transfer. The system can working at room temperature as a thermo electric cooler (Peltier Element) is integrated into the SDD chip. The dynamic range is about 1 keV to 10 keV. Test results indicated high energy resolution Full Width at Half Maximum (FWHM), which is better than 160 eV @ 5.9 keV with the incoming photon of radioisotopes (55Fe).
