Max. Echo Length Options:

Options:
-100 to 0 dB in steps of 1 dB.
The threshold value for single echo detections. Also lower
boundary for the computation of TS distribution classes
in the TS tables.
Options:
0.0 to 10.0 in steps of 0.1.
For a single echo detection to occur the normalized echo
length (echo length between the 6 dB points relative to
the peak value divided by the duration of the transmitted
pulse) must exceed this parameter.
0.0 to 10.0 in steps of 0.1.
A single echo detection requires the normalized echo
length to be less than the max echo length setting.
Options:
0.0 to 6.0 dB in steps of 0.1 dB.
The correction value returned from the transducer gain
model must not exceed the max gain compensation
setting. (This is the one-way max. gain compensation, the
two-way max. compensation will be 12 dB).
All echoes outside the angle corresponding to the chosen
gain compensation are skipped. Thus one can reduce the
sample volume (beam angle) by choosing a lower value
for max. gain compensation.
