The performance of silicon‐drift‐detector (SDD) arrays and digital electronics designed for X‐ray absorption spectroscopy in the fluorescence excitation mode is reported. Different detectors have been manufactured and tested: two single‐channel SDDs with different active areas (10 mm 2 and 1 cm 2 ) and a monolithic 2 cm 2 SDD with eight readout anodes. The energy resolution varies between 160 and 170 eV FWHM. A new digital multichannel shaping amplifier has been produced. Its performance is presented in comparison with that of a standard commercial shaper.
