Ww - Mode 1 Pings Before Mode 4 Re-Acquire; Wy - Mode 1 Bandwidth; Table 30: Wv-Command Maximum Setting (20 Degree) - Teledyne WORKHORSE Operation Manual

May 2015
Note that the minimum setting of the WV command is WV002 and the maximum setting due to
internal processing limitations is limited based on the setting of the bandwidth command, WB.
WV is limited to 330 cm/s in Narrow bandwidth mode (WB1), which increases the profiling
range by 10% compared to Broad bandwidth mode (WB0).
When the WB command is set to WB0, the max value is WV700.
In either case, while you can set a value as low as 2 cm/s, this will likely cause ambiguity errors.
TRDI recommends setting WV to ≥ 100cm/s for most applications.
The 1.5 value is a safety factor.

WW – Mode 1 Pings before Mode 4 Re-Acquire
Purpose Sets the number of Mode 1 pings sent before a Mode 4 ping is attempted.
Format WWnnn
Range nnn = 0 to 999 pings
Default WW4
Recommended Setting. Leave this command at the default setting.
Description WW is the number of Mode 1 pings generated by the H-ADCP before a Mode 4 ping is
tried. The H-ADCP uses this value when Mode 4 is in use and the bottom is lost. If
WW=0, the H-ADCP continually tries to generate Mode 4 pings.
For H-ADCP systems, the profiling mode is set to Mode 1 and can not be changed to Mode 4.
WY – Mode 1 Bandwidth
Purpose Sets the profiling Mode 1 bandwidth (sampling rate) and the radial ambiguity velocity.
Format WYb,aaa
Range b = 0 (Wide), 1 (Narrow)
aaa = 2 to 700 cm/s (330 cm/s in Narrow mode)
Default WY1,185
Recommended Setting. The default setting for this command is recommended for most applications.
Description The WY command sets the WB and WV commands using one command. For more infor-
mation, see
Example Setting the WY command to WY0,175 will set the WB command to WB0 and the WV
command to WV175.
