Trigger types
NOTE. This online help documents features and options available for several instrument models. Your instrument may not have
every feature discussed in this online help, depending on its configuration.
From the Trig menu, select A Event Trigger Setup or B Event Trigger Setup.
To use. Click the Select button for selecting the trigger type in the Trigger Selection dialog box.
The triggers type available are listed as follows:
Edge trigger. This is the simplest and most commonly used trigger type, used with both analog and digital signals. An edge
trigger event occurs when the trigger source passes through a specified voltage level in the specified direction (rising or falling
signal voltage).
Bus trigger. This trigger is used with both analog and digital signals used to set up parallel buses or a serial buses. A bus trigger
event occurs when the instrument detects a bus pattern that you specify for a parallel bus, or a bus cycle you select for a serial
bus.
NOTE. This online help supports many oscilloscope models from Tektronix. This feature is only available on some models.
Glitch trigger, Transition trigger, Pattern trigger, Runt trigger, Window Trigger, State trigger, Width trigger, Timeout trigger, and
Setup/Hold trigger
Pulse trigger. Pulse trigger on B event is not available on MSO/DPO5000B Series instruments.
These are special-purpose triggers that are primarily used with digital signals. The following types of pulse triggers are available:
Glitch, Runt, Window, Width, Transition, and Timeout. Pulse triggers are available on the main and B event triggers only.
Logic trigger. Logic trigger on B event is not available on MSO/DPO5000B Series instruments.
These are special-purpose triggers that are primarily used with digital logic signals. Two of the types, Pattern and State, trigger
the instrument based on the Boolean operator that you select for the trigger sources. A third type, Setup and Hold, triggers when
data in one trigger source changes state within the setup and hold times that you specify relative to a clock in another trigger
source. Logic triggers are available on the main and B event triggers.
