Triggering

Triggering

In order to clearly display and analyze a signal the instrument needs a consistent start point for data capture. This is called triggering and it is controlled by an instrument's trigger system.

Triggering concepts and curriculum are also covered in our introductory lab guide.

Introduction to Triggering

Overview of what triggering is, why it is important, and some key terminology associated with it.



Using Edge Trigger

Edge triggering uses the rising or falling edge of a signal to trigger the oscilloscope.

 



Using Pulse Trigger

Pulse triggering uses the width of a pulse to determine when to trigger the oscilloscope.

 



Using Delay Trigger

Delay triggering is used to trigger when time differences between signal transitions either fail to meet minimum thresholds or exceed maximum thresholds.

 



Using Nth Edge Trigger

Nth Edge Trigger is used to trigger after a defined number of pulses have passed helping trigger on and debug complex serial patterns

 



Using Setup and Hold Trigger

Setup and Hold trigger is used to verify the minimum amount of time that data is stable after a clock transition.

 



Using Runt Trigger

Runt triggering is used to trigger the oscilloscope when a runt pulse fails to pass both the low and high trigger points.

 



Using Serial Bus Triggering

Serial triggering is used to trigger the oscilloscope based on specific behavior, command, or data set found on the serial bus

 



Using Pattern Triggering

Pattern triggering is used to trigger the oscilloscope when multiple signal conditions are met in a digital system.

 



Using Duration Triggering

Similar to pattern triggering, duration triggering is used to trigger the oscilloscope when multiple signal conditions are met based on how long the desired state persists

 



Using Slope Triggering

Slope triggering is used to trigger the oscilloscope based on the rise or fall time of a signal
