Water Profiling Commands

The following commands define the criteria used to collect the water-profile data.

Standard Water Profiling Commands

This section lists the most often used Water Profiling commands.
>w?
WD = 111 100 000 --------- Data Out (Vel;Cor;Amp
WF = 0175 ---------------- Blank After Transmit (cm)
WN = 030 ----------------- Number of depth cells (1-255)
WP = 00030 --------------- Pings per Ensemble (0-16384)
WS = 0800 ---------------- Depth Cell Size (cm)
WV = 185 ----------------- Mode 1 Ambiguity Vel (cm/s radial)
>expert?
Expert Mode is OFF
>experton
Expert Mode is ON
>w?
WA = 255 ----------------- False Target Threshold (Max) (0-255 counts)
WB = 1 ------------------- Bandwidth Control (0=Wid,1=Nar)
WC = 064 ----------------- Correlation Threshold
WD = 111 100 000 --------- Data Out (Vel;Cor;Amp
WE = 1500 ---------------- Error Velocity Threshold (0-5000 mm/s)
WF = 0175 ---------------- Blank After Transmit (cm)
WI = 0 ------------------- Clip Data Past Bottom (0=OFF,1=ON)
WJ = 1 ------------------- Rcvr Gain Select (0=Low,1=High)
WL = 000,005 ------------- Water Reference Layer:
WN = 030 ----------------- Number of depth cells (1-255)
WP = 00030 --------------- Pings per Ensemble (0-16384)
WQ = 0 ------------------- Sample Ambient Sound (0=OFF,1=ON)
WS = 0800 ---------------- Depth Cell Size (cm)
WT = 0000 ---------------- Transmit Length (cm) [0 = Bin Length]
WU = 0 ------------------- Ping Weighting (0=Box,1=Triangle)
WV = 185 ----------------- Mode 1 Ambiguity Vel (cm/s radial)
WW = 004 ----------------- Mode 1 Pings before Mode 4 Re-acquire
WY = 1,185 --------------- WM 1: Bandwidth (0=WB, 1=NB), Amb. Vel.(cm/s)

WA - False Target Threshold Maximum

Purpose Sets a false target (fish) filter.
Format WAnnn
nnn = 0 to 255 counts (255 disables this filter)
Range
Default WA255
Recommended Setting. The default setting for this command is recommended for most applications.
Description The H-ADCP uses the WA-command to screen water-track data for false targets (usually
fish). WA sets the maximum difference between echo intensity readings among the four
profiling beams. If the WA threshold value is exceeded, the H-ADCP rejects velocity data
on a cell-by-cell basis for either the affected beam (fish detected in only one beam) or for
the affected cell in all four beams (fish detected in more than one beam). This usually oc-
curs when fish pass through one or more beams.
A WA value of 255 turns off this feature.
