User Setup - Lists the setup used during data collection for each sampling burst type (1/2/3):
o
Number of bursts
o
Sample rate (Hz)
o
Burst interval (s)
o

o
Record (Yes/No) - Amplitude / Correlation data, Compass data, Sensor data, Statistical
data, External Sensor data, External Pressure data, CTD data
o
Number of bytes per burst
o
Velocity range index

o
Magnetic Declination - Can be changed during post-processing.
o
Coordinate System - Beam, XYZ, or ENU (East-North-Up)
o
Advanced - Shows the Temperature Mode, Default Water Temperature, Default Water
Salinity, and Default Speed of Sound.
12.3.6. Analysis Menu
This menu lets you view data in various formats. Each of these selections has its own criteria for
which parameters to view. These items are available only in ViewHydraPro.
•
Histograms - Allows you to view histograms of velocity, amplitude, correlation, magnitude,
direction, temperature, and external pressure. Various options are available while viewing the
histogram, including beam/coordinate selection, normal distribution, alter grade values, ex-
port the data in an ASCII format, copy to clipboard, print the graph. Table 7 lists the file-
naming format for exported histogram files.
•
Spectra - Allows you to view graphs of auto-spectra (U, V, W), cross-spectra (U-V, U-W,
V-W), coherence function (U-V, U-W, V-W), and transfer function (U-V, U-W, V-W). Vari-
ous options are available while viewing the graph, including: Get Slope (drag cursor over the
area of interest), 5/3 Slope (drag cursor over the area of interest), NFFT, Window Type, ex-
port the data in an ASCII format, copy to clipboard, print the graph, zoom-in/out. Table 7
lists the file-naming format for exported spectra files.
•
Scatter Diagrams - Allows you to view scatter diagrams based on X-Y, X-Z, or Y-Z axes.
You can also choose to show/hide the mean vector, copy to clipboard, or print the graph.
