SIGNL
The submenu permits the direct graphical display of several
transducer signals. Specifically, the signals listed in Table 2-5 below
may be viewed in this format.
Note: Only one side of the display (either left or right) can show a
signal at any given time.

Refer to Figure A-5 on page A-5 and complete the following steps to
display the transducer signals. Press the appropriate side of the
[SCREEN]
key to activate the desired pane of the display screen, then
proceed as follows:
Note: For this discussion, it is assumed that the left pane of the
display screen is active. If the right pane is active, it is only

prompt does not appear and the Measure type
signals are not available. To access these signals, the
burst technique must be selected.
The signal graph is a plot of signal amplitude (y-axis) vs. time in
microseconds (x-axis). When the
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.
