Triggering the Multimeter
At power- on, the default trigger source is auto- triggering.
Auto- triggering takes continuous readings at the fastest rate
possible for the selected measurement configuration. To
make a trigger measurement, follow the steps below:
1 Configure the multimeter for the measurement by
selecting the function, range, resolution, and so on.
2 Specify the multimeter’s trigger source. Choices are as
below:
• Software (bus) trigger from the remote interface.
• An immediate internal trigger (default trigger source).
• An external trigger from an external trigger pulse.
3 Ensure that the multimeter is ready to accept a trigger
from the specified source (called the wait- for- trigger
state).
Immediate Triggering
The immediate triggering mode is available from the remote
interface only.
In the immediate trigger mode, the trigger signal is always
present. When you place the multimeter in the
wait- for- trigger state, the trigger is issued immediately. This
is the default trigger source for remote interface operation.
• Remote Interface Operation: The following command selects
the immediate trigger source:
TRIGger:SOURce IMMediate
The CONFigure and MEASure? commands automatically
set the trigger source to IMMediate.
Refer to the Keysight 34450A Programmer’s Reference
Helpfile for complete description and syntax for these
commands.
