The meter assumes as main signal (i.e. the signal with zero delay) the “echo” with the
highest level among all the detected signals.
To change the marker position, using the Standard Navigation Mode highlight the
echoes position item located at the top right side of the display and sweep the marker
position. The current marker position is shown on the display through a vertical dotted
row.
The marker can also be moved in the negative portion of the selected domain (both
time and space). Into the negative portion the echoes:
x occurring before the main signal (PRE ECHOES) and
x whose level is below the main signal level
can be found.
