A MEM_TWEAK is included in this trigger to set the WBR/DUST antenna           
multiplexor to the Lp position following WBR or DUST data acquisitions.       
                                                                              
Trigger 54 adds WBR data, increasing the load on the BIU handler. This        
addition requires that the WFR data rate be depressed by reducing the         
sampling interval to 25 seconds. Decreasing the interval below this limit     
causes loss of WFR traffic on the LRP. This also allows the data to be packed 
on the DCP, further decreasing the load on LRP.
