Graphical output
|
||||
----------------
|
||||
|
||||
A graphical interface is available for exploration of a captured
|
||||
pattern. This interface is invoked if the option -g is set. Note
|
||||
that sample rate, trigger, etc., still have to be set up via the
|
||||
command line. Example:
|
||||
|
||||
# ubb-la -f 12 -t 0/8 -g
|
||||
|
||||
In the GUI, the following keys are available:
|
||||
|
||||
Left/Right Pan the waveform left/right
|
||||
Up/Down Zoom in/out
|
||||
Space Set the user origin (upward-facing green triangle)
|
||||
at the current position and display the time to
|
||||
the center position (downward-facing blue triangle).
|
||||
Pressing space again removes the user origin.
|
||||
Enter/Q Quit
