We also have a Ramp DACs mode designed to test all of the DAC channels for calibration errors, missing codes, etc. In this mode, all of the DAC channels are simultaneously ramped from 0 to 255, with a full housekeeping set collected at each DN level. This mode uses a modified Stripchart HK Frame to store the HK data, in which the satellite time is replaced by the DN value being written to the DACs. (NOTE: This mode has been disabled in the flight software to ensure that it is not used in flight.)
