Immediate Triggering
This 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 34410A/11A/L4411A Programmer’s Reference Help for
a complete description and syntax for these commands.
