The Hitomi Soft X-ray Spectrometer (SXS) was a pioneering non-dispersive imaging x-ray spectrometer with 5 eV FWHM energy resolution, consisting of an array of 36 silicon-thermistor microcalorimeters at the focus of a high-throughput soft x-ray telescope. Here, the instrument enabled astrophysical plasma diagnostics in the 0.3–12 keV band. We introduce the SXS calibration strategy and corresponding ground calibration measurements that took place from 2012–2015, including both the characterization of the microcalorimeter array and measurements of the x-ray transmission of optical blocking filters.
