7. If T
rigger When is set to a limit value, use the Time Limit field to set the runt signal time constraints.
Trigger on a logic event
Use the Logic trigger to trigger the oscilloscope when the specified logic conditions occur on the inputs.
To trigger on a Logic event:
1. Double-tap the Trigger badge to open the Trigger configuration menu.
2. Tap Trigger Type and select Logic. See Logic Trigger configuration menu on page 216.
3. Set Use Clock Edge? to enable or disable finding logic patterns that occur on the clock edge of a specified channel.
4. Tap Logic Pattern Define Inputs and use the Logic Trigger menu to set the logic state and the signal logic threshold level for each
analog or digital signal.
5. Tap Clock Source and select the signal to use as the clock.
6. Use the Clock Edge controls to set the signal transition edge to use to evaluate the logic condition at the clock transition.
7. T
ap the Clock Threshold field and set the threshold level that the clock signal must pass through to be considered a valid transition.
The clock threshold value is independent of the input signal threshold(s).
8. Tap Trigger When and select the waveform condition on which to trigger when not using a clock edge.
9. T
ap Define Logic and set the logic condition that must occur with all specified signals to cause a trigger event.
