ADVField Software Manual (September 1, 2001) 18
File names must be given without an extension. The programs assume the ADV binary data file
has the extension
.ADV
and assigns the output file an extension based on the type of data being
extracted (extensions are
.AMP
,
.COR
,
.HPR
,
.SEN
,
.SNR
, and
.VEL
). If no output file is specified,
the programs assign the same root name as the binary data file.
Note
: The
[probe #]
parameter is only used with ADVLab systems, which are not discussed in
this document.
The
[first sample]
and
[last sample]
permit you to extract a limited portion of the data. If
they are not specified, the programs extract all samples contained in the binary data file.
For example,
GETVEL TEST1 TEST 100 199
extracts the velocity data for samples 100 through 199 in the binary data file
TEST1.ADV
and
sends the output to ASCII file
TEST.VEL
.
Similarly, the command
GETSNR TEST1 TEST
extracts the SNR data from all samples from binary data file
TEST1.ADV
and sends the output to
ASCII file
TEST.SNR
.
These programs generate output files in a tabular ASCII format with one line per sample. With
the exception of the programs
GETHPR
and
GETSEN
(which are discussed at the end of this sec-
tion), the output files use the following format for each line.
T Event Probe# DATA1 DATA2 DATA3 Probe# DATA1 DATA2 DATA3
where
T
is the time in seconds from the start of the first sample, and
Event
is the value of the
event counter (for marking points during the data file using <F7>) at the time the sample was col-
lected. The rest of the line contains the probe number followed by its corresponding data. Table 2
summarizes the values and units output by the data sample conversion programs.

The programs
GETHPR
and
GETSEN
extract data from the optional sensors on the ADVField. The
first three values on each line are time (in seconds from the start of the file), event counter, and
probe number. If the compass/tilt sensor is installed, both
GETHPR
and
GETSEN
extract heading,
pitch, and roll (in degrees) as the next three data values. If either the temperature or pressure sen-
sor is installed, but the compass/tilt sensor is not,
GETSEN
extracts temperature (in either °C
or °F) and pressure (in either dBar or psi) as the next two data values. If compass/tilt, tempera-
ture, and pressure are
installed,
GETSEN
extracts five data values in the following order: heading,
pitch, roll, temperature, and pressure.
