Trigger 3C Description

Sequence: C19,...
Trigger 3C ( High Resolution HFR )

This trigger is designed to provide HFR data at its highest spectral resolution. Data acquisition continues for the LFR, MFR, and WFR. The HFR mode is detailed below.

Receiver	Frequency Range	Sensor	Cycle Time	Snapshot Size
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	42.125 seconds
WFR	.05 - 2.5 KHz	EX, EW, BX, BY, BZ	96 seconds	2048

The HFR is in high spectral resolution mode . No direction-finding is done. This mode is defined by:

Bands ABC require 3.12 sec to complete, H1 requires 13.9 sec, and H2 requires 21.75 sec for a total of 38.8 sec per sweep. Data collection and output limits the snapshot time to about 42 seconds.
