Abstract We present the predicted response of the Solar-A Soft X-Ray Telescope (SXT) to various solar targets. From prelaunch calibrations of the SXT flight mirror, X-ray filters, and CCD detector, we are able to predict exposure times and image cadence for a representative range of temperatures and emission measures of the coronal plasma. We find that the SXT is very sensitive; it should be able to observe active regions and flares at its nominal cadence (2 s) with exposure times ranging from 0.0001 to 1 s. The SXT temperature diagnostic capabilities are presented for various combinations of the X-ray filters. SXT data can be used to reproduce accurately the temperature and emission measure of an isothermal plasma. However, if there is a wide distribution of temperatures in a pixel, reconstructing the original differential emission measure distribution becomes more uncertain.
