Trigger
The trigger is used to display the sampled data stored in the acquisition memory as
waveforms on the screen. The trigger is activated when the specified trigger condition is
met.
Trigger Source «For procedures, see section 7.2.»
Trigger source refers to the signal that is used in checking the trigger condition.
Trigger Slope «For procedures, see section 7.3.»
Slope refers to the movement of the signal such as the movement from a low level to a
high level (rising) or the movement from a high level to a low level (falling). When the
slope is used as one of the trigger conditions, it is called a trigger slope.
Trigger Level «For procedures, see section 7.3.»
Trigger level refers to the level that is used to judge the passing level of the trigger slope
or the condition of the trigger source.
Trigger Type «For procedures, see section 7.3, 7.4.»
There are two types of triggers, edge trigger and window trigger.
Edge trigger
A trigger occurs when the trigger source rises above or falls below a preset trigger
level. The trigger source can be selected as the input signals of CH1 through CH8 or
as the external trigger input signal.
Trigger Level
A trigger occurs at this point if rising edge ( ) is selected.
Trigger Source
Window trigger
A certain window width is set and a trigger occurs when the trigger source level enters
this window (IN) or exits from this window (OUT).
