Trigger 28 (Interplanetary Cruise with Direction-Finding & Dust & LP Sweeps)  
                                                                              
     This mode is designed to provide a low bit-rate Survey with low temporal 
and spectral resolution for periods during cruise. No Wideband or Waveform    
measurements are made. The entire RPWS frequency range (1 Hz - 16 MHz) is     
covered.

The HFR is in direction-finding mode for the frequency range from 3.6 KHz to  
2 MHz.  Thus, measurements are made on all three monopoles EU, EV and EW. For 
higher frequencies only EX and EW are used.

Bands ABC require 6.40 sec to complete, H1 requires 6.07 sec, and H2 requires 
6.36 sec for a total of 18.83 sec per sweep. However, to keep the bit rate    
down the HFR only performs one complete sweep every 64 seconds.               
                                                                              
Starting in C26, dust detection using the EZ sensor was added, and            
also periodic Langmuir Probe sweeps every 8128 seconds.
