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:
Press 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:
Press When , then rotate the multifunction knob to select the trigger condition,
and then press down the knob to select the trigger condition. You can also press
When continuously to select the trigger condition or enable the touch screen to tap
the desired trigger condition and select it.
⚫
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
oscilloscope triggers when the positive slope time of the input signal is smaller
than the specified time.
⚫
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 lower limit time and smaller than the specified upper limit
time.
⚫
When you select "Falling" for the edge type, ">" for trigger condition, the
oscilloscope triggers when the negative slope time of the input signal is greater
than the specified time.
⚫
When you select "Falling" for the edge type, "<" for trigger condition, the

When " > " or " < " is set to trigger condition, press Lower or Upper , and then
rotate the multifunction knob to set the lower limit value or the upper limit
value. You can also use the pop-up numeric keypad to set it. The available range
of the slope time is from 800 ps to 10 s.
⚫
When " <> " is set to trigger condition, press Upper and Lower , and then rotate
the multifunction knob to set the upper limit value and the lower limit value.
You can also use the pop-up numeric keypad to set them.
Note: The lower slope time limit must be smaller than the upper slope time
