END_OBJECT = TEXT END 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.
