6.7.2 Slope Trigger
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
A and B with the positive edge as shown in the figure below.

•
<= (less than a time value)
: Trigger when the positive or negative slope time of the input signal is lower than
the specified time value.
•
>= (greater than a time value)
: Trigger when the positive or negative slope time of the input signal is greater
than the specified time value.
•
[- - . - -] (within a range of time value)
:Trigger when the positive or negative slope time of the input signal
is greater than the specified lower limit of time and lower than the specified upper limit of time value.
•
- -][- - (outside a range of time value)
: Trigger when the positive or negative slope time of the input signal is
greater than the specified upper limit of time and lower than the specified lower limit of time value.
