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.
Receiver Frequency Range Sensor Cycle Time Snapshot Size -------- --------------- ---------------- ---------------- ------------- LFR 1Hz-25Hz EX,BX 32.000 Seconds MFR 25Hz-12KHz EX,BZ 32.000 Seconds
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 Bands ABC and Band H1, but for Band H2, only on the dipole EX.
This mode is defined by:
Correlations Channels Integ. Size Frequency
Band Ant. Auto- Cross- per Band df Period Rep Steps kHz Start - Stop
---- ---- ----- ------ -------- -- ------ --- ----- ---- ------------
ABC 2E y y 32 y 1000 1 3.6-319KHz

HF2 1E n n 1 n 80 1 71 200 2.075-16.275MHz
Bands ABC require 6.340 sec to complete, H1 requires 6.071 sec, and
H2 requires 4.686 sec for a total of 17.097 sec per sweep. The hfr
cycle time is 64.000 seconds.
