Triggering The Multimeter - Agilent Technologies 34405A User's And Service Manual

Triggering the Multimeter

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:
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.

Software (Bus) Triggering
The bus trigger mode is available from the remote interface only.
The bus trigger mode is initiated by sending a bus trigger command, after
selecting BUS as the trigger source.
• The TRIGger:SOURce BUS command selects the bus trigger source.
