SYSTEM PERFORMANCE AND DATA TYPES
A snippets data sample contains backscatter data from the 'footprint' on the seabed illuminated
by a single sonar ping. The number of snippets in a swath is a function of the number of sonar
beams. The length of each snippet depends on the operating mode, beam number, and depth. All
of these settings may be selected by the operator.
Bottom detection point
Each snippets data packet contains pertinent information such as time stamp, sequential ping
number, sample rate, sound velocity, and operator settings such as power, gain, absorption, and
range scale.
Refer to the 7k Data Format Definition for further information regarding snippet data output (see
also Appendix E Reference Documentation).

of samples on each side of the bottom detection point.
Export this data as a "snippet" for each beam.
