Chapter 2. Displaying Data
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bar has been replaced by a status line in standard video that shows the signal amplitude and the time (in microseconds)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.

Option Bar Choice Description
[F1] = <CURS
Move the cursor to the left and display amplitude and time in the status line:
(i.e.
107 686.798mi)
[F2] = CURS>
Move the cursor to the right and display amplitude and time in the status line:
(i.e.
107 686.798mi)
[F3] = <PAGE Display the previous page
[F4] = PAGE> Display the next page
[
+ [F1] = 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 mes-
sage 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.)
