Trigger 2 Description

Sequence: C7 (Venus-1) Trigger 2 (Venus-1 Science Mode) This mode is designed to provide HFR data to search for lightning during the Venus-1 gravity assist flyby. No LFR, MFR, Wideband or Waveform measurements are made. The frequency range 71 KHz - 16 MHz is covered. This Trigger writes the data to RPWS memory, where it was later MRO'd to telemetry.

The complete sweep takes about 2 seconds. Four Sweeps were collected in each HFR analysis record, with the time between each record being 7.875 seconds.
