Trigger level

In edge trigger, the level at which the actual trigger takes place, is called the trigger level. This level corresponds with the firing level.

In window trigger, the upper level of the trigger window is controlled with the trigger level control in the software.

Trigger level can be set for each channel individually.

Changing the trigger level of a channel in the Multi Channel software can be done in various different ways:

  • Right-clicking the channel in the Object Tree and selecting Trigger level in the popup menu. The level can then be set as a percentage of the full scale input range of the channel by selecting one of the pre defined percentage values. 50% corresponds with 0 Volt. A User defined... setting is available that also allows to set the trigger level as a voltage.
  • Using hotkeys F7 and F8 in combination with the appropriate channel selection hotkey(s)
  • Using the trigger symbol on the axis that serves as trigger source:
    • For trigger type Rising slope Rising edge symbol drag the whole trigger symbol to change the trigger level and keep the trigger hysteresis unchanged. Dragging the upper edge of the symbol will change the trigger level and trigger hysteresis simultaneously.
    • For trigger type Falling slope Falling edge symbol drag the whole trigger symbol to change the trigger level and keep the trigger hysteresis unchanged. Dragging the lower edge of the symbol will change the trigger level and trigger hysteresis simultaneously.
    • For trigger type Inside window Inside window and Outside window Outside window drag the whole trigger symbol to change the upper level and keep the window size unchanged. Dragging the upper edge of the symbol will change the upper level level and window size simultaneously.
  • Right-clicking the trigger symbol on an axis and selecting Trigger level in the popup menu. The level can then be set as a percentage of the full scale input range of the channel by selecting one of the pre defined percentage values. 50% corresponds with 0 Volt. A User defined... setting is available that also allows to set the trigger level as a voltage.
  • Clicking the increase/decrease trigger level buttons Increase trigger level and Decrease trigger level on the channel toolbar
