Triggering the Multimeter

50
From the front panel (Local mode), the multimeter always
auto–triggers. Auto triggering takes continuous readings at
the fastest rate possible for the selected measurement
configuration.
From the remote interface, triggering the multimeter is a
three–step process:
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 a
software (bus) trigger from the remote interface or an
immediate internal trigger (default trigger source).
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 Agilent 34405A Programmer's Reference for
complete description and syntax for these commands.
Software (Bus) Triggering
The bus trigger mode is available from the remote interface
only.
