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.
Trigger Type:
Press Type, rotate to select "Slope" and press down . At this point, the
trigger setting information is displayed at the upper right corner of the screen.
For example,
. The trigger type is slope trigger; the trigger source
is CH1; the difference between the upper limit of trigger level and the lower limit of
trigger level is 400 mV.
Source Selection:
Press Source to switch the signal source and select CH1-CH4. For the details, please
refer to the introduction in " Trigger Source". The current trigger source is
displayed at the upper right corner of the screen.
Note: Select channel with signal input as trigger source to obtain stable trigger.
Slope Condition:
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.

Press When to select the desired slope condition.

: trigger when the positive slope time of the input signal is greater than
the specified time.
 : trigger when the positive slope time of the input signal is lower than the
specified time.
 : trigger when the positive slope time of the input signal is greater than
the specified lower limit of time and lower than the specified upper limit of time.
 : trigger when the negative slope time of the input signal is greater than
the specified time.
 : trigger when the negative slope time of the input signal is lower than
the specified time.
