Chapter 5 To Trigger the Oscilloscope

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.

Trigger Type:
Click Type to select "Slope". Then, the current trigger setting information is
displayed at the upper-right corner of the screen, as shown in the figure below.
Source Selection:
Click Source to switch the trigger source and select CH1-CH4. For details, refer to
descriptions in "Trigger Source". The current trigger source is displayed at the
upper-right corner of the screen.
Note: Only when we select the channel (that has been input with signals) as the
trigger source, can we obtain a stable trigger.
Edge Type:
Click Slope continuously to select the input signal edge on which the oscilloscope
triggers.
Rising: triggers on the rising edge of the input signal.
⚫
Falling: triggers on the falling edge of the input signal.

Slope Condition:
Click When to select the trigger condition.
When you select "Rising" for the edge type, ">" for trigger condition, the

oscilloscope triggers when the positive slope time of the input signal is greater
than the specified time.
When you select "Rising" for the edge type, "<" for trigger condition, the
