This menu is identical to the DISPLAY/Echogram Menu except for SCOPE in
the PRESENTATION submenu. For the other menu descriptions, refer back to
paragraph 2.4.1 The DISPLAY/Echogram Menu. Also refer to the description of
the printer echogram in paragraph 1.2.4
Presentation Options:
NORMAL, WH. LINE and CONTOUR as in the
DISPLAY/Echogram Menu.
SCOPE presentation is intended for special purpose studies
of the echo return and causes an oscilloscope-like plot of a
single ping to be printed. Echo amplitude and directional
angles are plotted; echo amplitude in units of dBW (referred
to the transducer terminals) and directional angles in units
of phase steps (64 phase steps = 180 electrical degrees). The
plot starts at the upper depth boundary of the super layer,
and a total of 300 samples (basic hardware sampling rate of
transceiver) is plotted. Note that no echogram is plotted
during the printout period. Refer to figure 4.
