ADFM Commands
depth cell. WE screens for error velocities in both beam and
transformed-coordinate data.
WF - WT Blank After Transmit
Purpose: Moves the location of first depth cell away from the trans-
ducer head to allow the transmit circuits time to recover be-
fore the receive cycle begins.
Format: WF nnnn
Range: nnnn = 0-9999 cm
Description: WF positions the start of the first depth cell at some radial dis-
tance from the transducer head. This allows the ADFM
transmit circuits time to recover before beginning the receive
cycle. In effect, WF blanks out bad data close to the trans-
ducer head, thus creating a depth window that reduces un-
wanted data in the ensemble.
WG - Percent Good Minimum
Purpose: Sets a good-data qualifier for water-track data.
Format: WG nnn
Range: nnn = 1 to 100%
Default: WG025
Description: WG sets the minimum percentage of water-track pings that
must be good in an ensemble before the ADFM flags the data
as good. If the percentage of water-track pings that are good
in an ensemble is below WG, the ADFM flags the data as bad.
WM - WT Profiling Mode
Purpose: Selects the application-dependent profiling mode used by the
ADFM.
Format: WM n
Range: n = 1,3,5
Description: WM lets you select an application-dependent profiling mode.
The chosen mode selects the types of pings transmitted. The
ping type depends on how much the water current is changing
from ping-to-ping and from cell-to-cell.
