Trigger 3E Description

Sequence: All
Trigger 3E mode

The instrument is assumed to be operating in trigger 28.

Command Byte Count: 6 Valid Command Count: 116

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.
