This mode is designed to provide a survey mode, with standard temporal        
resolution and spectral resolution.  Both low-frequency and high-frequency    
WFR measurements are made, using a "toggle" mode, although a fixed gain       
(maximum) rather than an auto gain mode is required until a future software   
update, scheduled for C35 (FSW V2.6). Dust detection is included. Langmuir    
Probe sweeps are performed every 640 seconds. A Sounder measurement is        
scheduled every 10 minutes. LFDR measurements are now made every 16 seconds,  
in anticipation of the LFDR toggle mode, coming with FSW V2.6, which will     
provide MFR2 replacement data.

The HFR is in a modified "Composite Survey" mode, which now includes          
both auto- and cross-correlations for H1.

Bands ABC require 3.16 sec to complete, H1 requires 5.47 sec, and H2 requires 
1.46 sec for a total of  10.09 sec per sweep. However, the time between       
analyses is set to 16 seconds to reduce the bit rate.  Every 600 seconds the  
HFR normal analyses are interrupted by a Sounder analysis.  The Sounder       
operation has a duration of approximately 40 seconds.  This Sounder analysis  
is defined by:
