2 Features and Functions
Triggering the Multimeter
The 34410A/11A/L4411A triggering system allows you to generate triggers either
manually or automatically, take multiple readings per trigger, and insert a delay before
each reading. The 34411A/L4411A also allows you to set a level for internal triggering,
and to set up pre-triggering.
Selecting a Trigger Source
Specify the source from which the multimeter will accept a trigger. The power–on
default is auto triggering from the front panel. Several types of triggering are described
in the sections that follow.
• Front Panel Operation:
• Press once to go to the single trigger mode. A single reading is taken, and
another reading is taken each time you press , or when a hardware trigger is
received on the Ext Trig connector.
• Press and select:
TRIGGER > AUTO To return to auto trigger mode.
TRIGGER > LEVEL To select internal (level) triggering (34411A only).
TRIGGER > HOLD To select reading hold mode.
TRIGGER > SETUP To enter the trigger setup menu.
• Remote Interface Operation: The following command selects the trigger source
from the remote interface:
TRIGger:SOURce {IMMediate>EXTernal|BUS>INTernal}
Where INTernal triggering applies only to the 34411A/L4411A.
Refer to the Keysight 34410A/11A/L4411A Programmer’s Reference Help for
a complete description and syntax for this command.
Auto Triggering (34410A/11A)
This mode is available from the front panel only.
The power–on trigger default mode for the multimeter is front panel operation, in auto
trigger mode.
• Auto triggering takes continuous readings at the fastest rate possible for the specified
measurement configuration (function, range, resolution, and so forth).
