Liipaisu

Jotta signaali selkeästi näytettäisiin ja analysoitiin, instrumentti tarvitsee johdonmukaisen lähtökohdan tiedonkeruuta varten. Tätä kutsutaan liipaisuksi ja sitä ohjataan instrumentin liipaisujärjestelmällä.

Johdanto liipaisuun

Yleiskuvaus siitä, mikä liipaisee, miksi se on tärkeä, ja siihen liittyvä keskeinen terminologia.


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.
