Slope
Trigger
Menu
Source
:
Press the source button to select any of CH1, CH2, CH3 and CH4. The selected source will be displayed on the upper
right corner of the screen.
Note: only selecting the channel with connected signals as the trigger source can obtain a stable trigger.
Trigger
Setting
:
Please refer to the content of Triggle Setting in the Edge Trigger section for more details.
Slope
Setting
:
Press the slop setup button to enter the slope setting menu.
Slope
:
Press the slope button to select slope trigger edge, the rising edge or the falling edge.
1
）
Rising edge: Performs slope trigger by using the rising edge of the trigger signal.
2
）
Falling edge: Performs slope trigger by using the falling edge of the trigger signal.
Condition
:
Press the condition button to select the trigger conditions: "
", "
", "
".
(1) >: Triggers when the slew rate of the trigger signal is greater than the set slew rate.
(2) <: Triggers when the slew rate of the trigger signal is less than the set slew rate.
(3) =: Triggers when the slew rate of the trigger signal is basically the same as the set slew rate.
Time
Setting
:
Adjust the Multipurpose knob to set the time.
Threshold
Value
:
Press the threshold button to select the threshold value: low level, high level, high and low level. You can also directly
press the LEVEL knob in the trigger control area to quickly switch between selections.
(1) Low level: The low level threshold can be adjusted by the LEVEL knob.
(2) High level: The high level threshold can be adjusted by the LEVEL knob.
(3) High and low level: The high and low level thresholds can be simultaneously adjusted by the LEVEL knob.
Note: The formula for calculating the slew rate is
(High level threshold - Low level threshold) ÷Time
For the set slew rate, the time here is the time setting value. For the slew rate of the trigger signal, the time here refers to
the time value between two intersection points where the high and low level intersect with the trigger signal.
