Expert Vertical Beam Profile Commands
Changing expert vertical beam commands may result in data analysis, visualization, or serious
errors in TRDI software.
#ZB – Vertical Beam Bandwidth
Purpose:
Sets the vertical beam profile bandwidth (sampling rate).
Format:
#ZBn
Range:
n = 0=Wide (25%), 1=Narrow (6.25%), -1 = same as WB command
Default:
#ZB-1
Recommended Setting. The default setting for this command is recommended for most applications.
Software warning: Changing this command may cause problems with TRDI display and processing
software.
Description: Narrow bandwidths allow the Sentinel V Real-Time to profile farther, but the standard de-
viation is increased by as much as 2.5 times.
#ZC – Vertical Beam Correlation Threshold
Purpose:
Sets the minimum threshold for correlation magnitude that vertical beam profile velocity
data must meet to be considered valid.
Format:
#ZCnnn
Range:
nnn = 0 to 255 counts, -1 = same as WC command
Default:
#ZC-1
Recommended Setting. The default setting for this command is recommended for most applications.
Description: The Sentinel V Real-Time uses #ZC to screen vertical beam profile data for the minimum
acceptable correlation requirements. The nominal (maximum) correlation depends on sys-
tem frequency and vertical beam profile depth cell size (#ZS). #ZC sets the threshold of the
correlation below, which the Sentinel V Real-Time flags the data as bad and does not aver-
age the data into the ensemble.
The default threshold is 64 counts. A solid target would have a correlation of 128 counts.
#ZD – Vertical Beam Data Out
Purpose:
Selects the vertical beam profile data types collected by the Sentinel V Real-Time.
Format:
#ZD v;c;a;p;s;*;*;*;*;wd, -1 = same as WD command
Range:
Firmware switches (see description)
Default:
#ZD 0000000001
Recommended Setting. The default setting for this command is recommended for most applications.
