Field Description
WF / Blank after Contains the blanking distance used by the H-ADCP to allow the transmit circuits time
Transmit to recover before the receive cycle begins (WF-command).
Scaling: LSD = 1 centimeter; Range = 0 to 9999 cm (328 feet)
Signal Processing Contains the Signal Processing Mode. This field will always be set to 1.
Mode
WC / Low Corr Contains the minimum threshold of correlation that water-profile data can have to be
Thresh considered good data (WC-command).
Scaling: LSD = 1 count; Range = 0 to 255 counts
cr# / No. code reps Contains the number of code repetitions in the transmit pulse.
Scaling: LSD = 1 count; Range = 0 to 255 counts
WG / %Gd Minimum Contains the minimum percentage of water-profiling pings in an ensemble that must
be considered good to output velocity data.
Scaling: LSD = 1 percent; Range = 1 to 100 percent
WE / Error Velocity This field, initially set by the WE-command, contains the actual threshold value used to
Threshold flag water-current data as good or bad. If the error velocity value exceeds this thresh-
old, the H-ADCP flags all four beams of the affected bin as bad.
Scaling: LSD = 1 mm/s; Range = 0 to 5000 mm/s
Minutes These fields, set by the TP-command, contain the amount of time between ping groups
in the ensemble. NOTE: The H-ADCP automatically extends the ensemble interval (set
Seconds
by TE) if (WP x TP > TE).
Hundredths
EX / Coord Trans- Contains the coordinate transformation processing parameters (EX-command). These
form firmware switches indicate how the H-ADCP collected data.
xxx00xxx = NO TRANSFORMATION (BEAM COORDINATES)
xxx01xxx = INSTRUMENT COORDINATES
xxx10xxx = SHIP COORDINATES
xxx11xxx = EARTH COORDINATES
xxxxx1xx = TILTS (PITCH AND ROLL) USED IN SHIP
xxxxxx1x = 3-BEAM SOLUTION USED IF ONE BEAM IS
xxxxxxx1 = BIN MAPPING USED
EA / Heading Align- Contains a correction factor for physical heading misalignment (EA-command).
ment
Scaling: LSD = 0.01 degree; Range = -179.99 to 180.00 degrees
EB / Heading Bias Contains a correction factor for electrical/magnetic heading bias
(EB-command).
Scaling: LSD = 0.01 degree; Range = -179.99 to 180.00 degrees
