An oscilloscope's trigger function synchronizes the horizontal sweep at the correct point of the signal. This is essential for clear signal characterization. Trigger controls allow you to stabilize repetitive waveforms and capture single-shot waveforms.
What is a trigger point oscilloscope?
The oscilloscope trigger function enables repetitive waveforms to be displayed on the screen in steady fashion. The trigger enables the timebase to start its scan at the same point on each repetition of the waveform.
What is the function of triggering?
The TRIGGER function retrieves the event, subevent, or name of the object or analytic workspace that caused the execution of a trigger program (that is, a TRIGGER_DEFINE, TRIGGER_AFTER_UPDATE, or TRIGGER_BEFORE_UPDATE program, or any program identified as a trigger program using the TRIGGER command).
Why is trigger necessary?
Triggers help the database designer ensure certain actions, such as maintaining an audit file, are completed regardless of which program or user makes changes to the data. The programs are called triggers since an event, such as adding a record to a table, fires their execution.27 ene 2015
What is trigger source in oscilloscope?
Triggers are the method by which an oscilloscope synchronises the voltage and time data of your waveform, enabling you to view your signal fixed to a voltage/time point to analyse it further. ... Trigger modes control how your scope will start to sweep your signal.8 nov 2018
What is oscilloscope trigger holdoff?
The Trigger Holdoff control quite simply provides a means to add an additional, user-defined delay to the re-arming of the trigger circuit, beyond the end of the sweep/retrace period. This gives the user some control over how rapidly, or how often, the oscilloscope can be triggered.20 mar 2013
What is single trigger in oscilloscope?
You can use the trigger (the singleshot is a specific type of trigger) function on an oscilloscope to capture a single event signal.
