Trigger 54 Description

Sequence: C18,...
Trigger 54 ( Fast 2.5KHz WFR )

This trigger is designed to provide 2.5 KHz WFR data with a high temporal resolution. Data acquisition continues for the LFR, MFR, HFR and WBR.

Receiver Frequency Range Sensor Time between Snapshots Samples per Snapshot
LFR 1 - 25 Hz EX, BX 32 seconds
MFR 25 Hz - 12 KHz EX, BZ 32 seconds
HFR 3.6 KHz - 16 MHz EX, EW 9.875 seconds
WFR .05 - 2.5 KHz EX, EW, BX, BY, BZ 25 seconds 2048
WBR .1 - 10 KHz EX 0.25 second 1024


The HFR is in CMS mode (Composite Mode Survey). No direction-finding is done. This mode is defined by:
