Header Data Format; Figure 47. Binary Header Data Format - Teledyne WORKHORSE Operation Manual

WorkHorse H-ADCP Operation Manual
Some data outputs are in bytes per depth cell. For example, if the WN-command (number of depth cells)
= 30 (default), WD command = WD 111 100 000 (default), WP command > 0, BP command > 0, the re-
quired data buffer storage space is 841 bytes per ensemble.
There are seven data types output for this example: Fixed Leader, Variable Leader, Velocity, Correlation
Magnitude, Echo Intensity, Percent Good, and Bottom Track.
20 BYTES OF HEADER DATA (6 + [2 x 7 Data Types])
59 BYTES OF FIXED LEADER DATA (FIXED)
65 BYTES OF VARIABLE LEADER DATA (FIXED)
242 BYTES OF VELOCITY DATA (2 + 8 x 30)
122 BYTES OF CORRELATION MAGNITUDE DATA (2 + 4 x 30)
122 BYTES OF ECHO INTENSITY (2 + 4 x 30)
122 BYTES OF PERCENT-GOOD DATA (2 + 4 x 30)
85 BYTES OF BOTTOM TRACK DATA (FIXED)
2 BYTES OF RESERVED FOR TRDI USE (FIXED)
2 BYTES OF CHECKSUM DATA (FIXED)
841 BYTES OF DATA PER ENSEMBLE
