END_OBJECT = TEXT END Trigger 40 Description Sequence: C18,... Trigger 40 ( Fast 25 Hz WFR ) This trigger is designed to provide 25 Hz WFR data with a high temporal resolution. Data acquisition continues for the MFR and HFR. Receiver Frequency Range Sensor Cycle Time Snapshot Size -------- ---------------- ------------------ ------------- ------------- MFR 25 Hz - 12 KHz EX, BZ 32 seconds HFR 3.6 KHz - 16 MHz EX, EW 7.375 seconds WFR 1 - 25 Hz EX, EW, BX, BY, BZ 20.75 seconds 2048 The HFR is in CMS mode (Composite Mode Survey). No direction-finding is done. This mode is defined by: Correlations Channels Integ. Size Frequency Band Ant.
