Explanation
This function enables the DL9000 to trigger when the input signal level passes through
the trigger level.
CH1 to CH4, EXT, or LINE
Trigger Source
You can set the trigger source to CH1 to CH4, EXT, or LINE.
External Signal
To trigger on an external signal received through the rear panel TRIG IN terminal, set the
trigger source to EXT.
Commercial Power Supply
To trigger on the commercial power supply that the DL9000 receives, set the trigger
source to LINE.
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)
Trigger Level
• The selectable range is 8 divisions within the screen. The resolution is 0.01 divisions.
For example, if the T/div setting is 2 mV/division, the resolution is 0.02 mV.
• You can reset the trigger level to the current offset voltage by pressing RESET.
