Trigger 52 Description

Sequence: C18,...
Trigger 52 ( High Resolution HFR )

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

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	57 seconds
WFR	.05 - 2.5 KHz	EX, EW, BX, BY, BZ	96 seconds	2048
WBR	.1 - 10 KHz	EX	0.25 second	1024

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 27.59 sec, and H2 requires 21.75 sec for a total of 52.46 sec per sweep. Data collection and output limits the snapshot time to about 57 seconds.
