2.9 Online Data Visualisation
All settings outlined below will NOT affect the data
quality and can be changed in post-processing. For the
“View” menu please see section 5.10 on pages 55 ff.
 Stacking & Smoothing (1)
o Used to reduce noise visible on screen
o Higher values will better suppress noise, but may also
remove small features, best keep values to “1” or “2”
 TVG (time variant gain) (2)
o Compensates for propagation loss
o Higher values may mislead in gain settings, best keep
at low value (e.g. zero)
 Median Filter (3)
o Removes spikes (e.g. interference), but may also
remove small features; use with care
 Resolution (4)
o “Amplitude” best for noisy data
o “High Resolution” (default) best for general purpose
o “Raw Data” best when looking for pipes/cables
 HF & LF Thresholds (5)
o Defines the visible dynamic range
o “Min Level” sets noise removal level
o “SRange” sets dynamic range
 Colours (6)
o Set colour mapping used for the echo plot
(rainbow colours or shades of grey)
 Display Style (7)
o Defines what echo plot(s) is/are shown
(LF+HF / LF only / HF only)
