WB - Bandwidth Control

Purpose Sets profiling mode 1 bandwidth (sampling rate). Narrow bandwidths allow the H-ADCP
to profile farther, but the standard deviation is increased by as much as 2.5 times.
Format WBn
Range n = 0 (Wide), 1 (Narrow)
Default WB1
Recommended Setting. The default setting for this command is recommended for most applications.
Description See table below.
Table 28: Bandwidth Control
Bandwidth
0 = Wide (25%)
1 = Narrow (6.25%)

WC - Low Correlation Threshold

Purpose Sets the minimum threshold of water-track data that must meet the correlation criteria.
Format WCnnn
nnn = 0 to 255 counts
Range
Default WC64
Recommended Setting. The default setting for this command is recommended for most applications.
Description The H-ADCP uses WC to screen water-track data for the minimum acceptable correlation
requirements. The nominal (maximum) correlation depends on system frequency and
depth cell size (WS). WC sets the threshold of the correlation below, which the H-ADCP
flags the data as bad and does not average the data into the ensemble.
The default threshold for all frequencies is 64 counts. A solid target would have a correlation of
255 counts.
