The slope trigger looks for a rising or falling transition from one level to another level in
greater than or less than a certain amount of time.
In the oscilloscope, positive slope time is defined as the time difference between the two
crossing points of trigger level line A and B with the positive edge as shown in the figure
below.
B
The upper limit of trigger level
A The lower limit of trigger level
