Solar X-ray Spectrometer (SOXS) onboard GSAT-2 Indian satellite was launched on 8 May 2003. The low energy module (SLD) of the instrument is built up with two solid state detectors - Si PIN and Cadmium-Zinc Telluride (CZT). The dynamic energy ranges for detectors are 4-25 keV (area 11.56 mm^2) and 4-56 keV (area 25 mm^2), respectively. Both detectors have superb temporal resolution (100 ms in the flare mode) as well as energy resolution of 0.8 keV for Si PIN and 1.7 keV for CZT. These parameters allow for analysis of the intensity, peak energy and equivalent width of the Fe-line complex at 6.7 keV and iron-nickel complex at 8 keV. The description of the instrument, its in-orbit performance and first results will be presented.
