Trigger 1 Description

Sequence: All
Trigger 1 (Internal Basic Survey Mode)
This mode is designed to provide a Survey with fast temporal resolution and standard spectral resolution for periods when an IEB has not been loaded. Periodic Waveform measurements are made. The onboard dust detector is activated, using the EZ antenna. The entire RPWS frequency range (1 Hz - 16 MHz) is covered.

Receiver	Frequency Range	Sensors	Time between Snapshots
LFR	1 - 25 Hz	EX, BX	16 seconds
MFR	25 - 12 KHz	EX, BX	32 seconds
WFR	.05 - 2.5 KHz	EX, EW, BX, BY, BZ	341 seconds
HFR	3.6 KHz - 16 MHz	EX, EW	9.875 seconds

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

Bands ABC require 3.16 sec to complete, H1 requires 5.05 sec, and H2 requires 1.46 sec for a total of 9.67 sec per sweep. Data collection and output limits the snapshot time to 9.875 seconds.
