2.6 Displaying the Transducer Signal (cont.)
Note:
If the
Skan
burst technique was selected in the
ACTIV
menu, the
Signal to Display
prompt does not appear and the
Measure type signals are not available. To access these signals, the
S/M
burst technique must be selected.
The signal graph is a plot of signal amplitude (y-axis) vs. time in microseconds (x-axis). When the
SIGNL
display screen
first appears, it may briefly remain blank. As soon as the signal is acquired, processed and loaded into the display
memory, the graph will appear. A
cursor
, which is displayed as a vertical line that extends the full height of the graph
window, is used to highlight any point in time along the x-axis.
The typical display screen shown has the
Sup
transducer signal listed to the left of the y-axis and there is a
message line
below the graph that initially indicates the starting date and time of the graphed signal. Notice that most of the locator
bar has been replaced by a
status line
in standard video that shows the signal amplitude and the time (in microseconds)
of the measurement at the current cursor location. However, there is still an inverse video
pointer
at the far right of this
line to indicate that additional option bar choices are available.

START
Move the cursor to the start of the current page and post the starting date and time in the
message line: (i.e.
ST: 451.798usec
)
[
+ [F2]
=
END
Move the cursor to the end of the current page and post the ending date and time in the
message line: (i.e.
END: 744.298usec
)
[
+ [F3]
=
YMAX
Display the maximum Y value, set to 128 divisions in arbitrary units, in the message line.
[
+ [F4]
=
T INC
Display the time increment value in the message line. This is based on the frequency of the
transducers (equal to 0.125
sec for a 1 MHz transducer).
[
+ [F1]
=
EXIT
Leave the graphical
SIGNL
display and return the display to the previous data format.
(The
[EXIT]
key on the keypad will also perform this function.)
