 # Known Issues
 
-* for PHA firmware, when the trigger rate changed, the Events per Agg need to be changed.
+* Although the Events/Agg used the CAEN API to recalculate before ACQ start, for PHA firmware, when the trigger rate changed, the Events per Agg need to be changed.
 * The Agg Organization, Event per Agg, Record Length are strongly correlated. Some settings are invalid and will cause the digitizer goes crazy.
+* load digitizer setting would not load everything, only load the channel settings and some board settings.
 * Sometimes, the buffer is not in time order, and make the trigger/Accept rate to be nagative. This is nothing to do with the program but the digitizer settings. Recommand reporgram the digitizer.
 * for 1740 QDC, RecordLenght is board setting, but readout is indivuial group.
+* FOr PHA, the trapezoid scaling and fine-gain register are calculated before ACQ start.
