The DL6000/DLM6000 triggers on trigger source edges (rising or falling edges). An edge refers to a
point where the trigger source passes through the trigger level.
Trigger level
The DL6000/DLM6000 triggers here when the trigger edge is set to rising ( ).
Trigger source
Trigger Source (Source)
Trigger source refers to the signal that is used to check the specified trigger conditions. You can set
the trigger source to one of the settings below.
A Channel from CH1 to CH4
The signal that is received through one of the front panel input terminals (terminals 1 through 4).
Logic (A0 to D7)
The signal that is received through the rear-panel LOGIC signal input port.
You can set the source signal to a bit from A0 to A7, B0 to B7, C0 to C7, or D0 to D7. (On 16-bit
models, you can select from bits A0 to A7 and C0 to C7.)
External Signal (EXT)
The signal that is received through the rear-panel TRIG IN input terminal.
The DL6000/DLM6000 Power Source (LINE)
The commercial power that the DL6000/DLM6000 is connected to.
The DL6000/DLM6000 only triggers on the rising edge.
Trigger Slope (Slope/Polarity)
When the Trigger Source Is EXT or a Channel from CH1 to CH4
You can select how the DL6000/DLM6000 will trigger on the trigger source signal.
The DL6000/DLM6000 triggers when the trigger source changes from a level below
the trigger level to a level above the trigger level (rising).
The DL6000/DLM6000 triggers when the trigger source changes from a level above
the trigger level to a level below the trigger level (falling).
Enter The DL6000/DLM6000 triggers when the trigger source level enters the specified
voltage range (when the window comparator is on).
Exit The DL6000/DLM6000 triggers when the trigger source level exits from the specified
voltage range (when the window comparator is on).
When the Trigger Source Is the Logic Signal
You can select which signal polarity the DLM6000 will trigger on. The DLM6000 detects the trigger
source polarity using the thresholds (see section 5.2) that you have set.
The DL6000/DLM6000 triggers on rising edges.
The DL6000/DLM6000 triggers on falling edges.
Trigger Coupling (Coupling)
You can select the trigger coupling when the trigger source is a channel from CH1 to CH4.
AC The DL6000/DLM6000 removes the DC component from the trigger signal.
DC
The DL6000/DLM6000 uses the trigger source as the trigger signal without making any
changes.
Note
• The trigger coupling is fixed at DC when the trigger source is set to Logic, EXT, or LINE.
