| + | See [[How to Change STIX Dynamic Time Binning]] |
| − | STIX uses dynamic time binning onboard to ensure that all onboard storage and telemetry is not wasted by having time bins that only have background counts. This scheme relies on 3 parameters:
| |
| − | * Minimum integration time
| |
| − | * Maximum integration time
| |
| − | * Maximum counts per bin.
| |
| − | As STIX accumulated counts, the end of the time bin is determined IF:
| |
| − | * The minimum integration time is exceeded
| |
| − | AND
| |
| − | * Maximum integration time OR maximum counts is reached.
| |
| − | | |
| − | Therefore to customise this scheme, we need to alter these parameters in the ASW (onboard application software).
| |
| − | | |
| − | == Procedure ==
| |
| − | Once Starlet has been open and an IOR or PDOR has been set up, do the following:
| |
| − | * Change STIX into Configuration mode. Be sure to truncate the calibration run if switching from Nominal mode.
| |
| − | * Click "Add Sequence" and select command sequence AIXF414A Load ASW Parameter v02. This enables you to change an application software parameter. In the pop-up window that appears set the following parameters:
| |
| − | ** Parameter ID = 312 (minimum integration time) or 313 (maximum integration time) or 314 (maximum counts)
| |
| − | ** Parameter subID = 0. This means you are changing the value of the parameters rather the min and max allowed values which have different subprocess numbers.
| |
| − | ** Integration times are given in units of 0.1s - 1. For example, 1s == 9 (1s / 0.1s - 1)
