8.7.3 Slope Trigger
In Slope trigger, the oscilloscope triggers 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. As shown in the figure below:
