Explanation
This function enables the DL9000 to trigger on a trigger source edge when the input
signal level meets the specified qualifications.
CH1 to CH4 or EXT
Trigger Source
You can set the trigger source to a channel from CH1 to CH4 or EXT.
Triggering on an External Signal
To trigger on an external signal received through the rear panel TRIG IN terminal, set the
trigger source to EXT.
Trigger Slope
You can set when to activate a trigger based on how the trigger source signal passes the
trigger level.
Triggers when the trigger source signal passes the trigger level from below the trigger
level to above the trigger level (rising edge)
Triggers when the trigger source signal passes the trigger level from above the trigger
level to below the trigger level (falling edge)
Enter
Triggers when the trigger source level enters the specified voltage range (when
window comparator is ON)
Exit
Triggers when the trigger source level exits from the specified voltage range (when
window comparator is ON)
Qualification
Set the state of each signal to H, L, or X that is used to enable the trigger function.
H
When the signal is high
L
When the signal is low
IN
When the signal level is within the set voltage range
(when the window comparator is ON)
OUT
When the signal level is outside the set voltage range
(when the window comparator is ON)
X
Not used as a trigger condition (Don’t care)
Logic
Select the logic to apply to the signal states: AND or OR.
AND
When the states of all set signals match
OR
When the state of any set signal matches
Trigger Level
This is the same as the edge trigger. See section 6.6 for details.
Note
You cannot set the qualification for the trigger source signal.
