Slope Trigger

Slope triggering sets the oscilloscope to trigger on the positive or negative slope of
the specified time. This trigger mode is applicable to ramp and triangle waveforms.
In this oscilloscope, positive slope time is defined as the time difference between the
two crossing points of trigger level line A and B with the rising edge; negative slope
time is defined as the time difference between the two crossing points of trigger level
line A and B with the falling edge. See the figure below.
