Internal Triggering In the internal trigger mode (remote interface only),
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
power-on trigger source for re mote interface operation.
To select the internal trigger source, send the following command.
The CONFigure and MEASure? commands automatically set the
trigger source to IMMediate.
TRIGger:SOURce IMMediate
Software (Bus) Triggering T he bus trigger mode is available only
from the remote interface. This mode is similar to the single trigger
mode from the front panel, but you trigger the multimeter by sending
a bus trigger command.
•To select the bus trigger source, send the following command.
TRIGger:SOURce BUS
•To trigger the multimeter from the remote interface (GPIB or RS-232),
send the *TRG (trigger) command. The *TRG command will not be
accepted unless the multimeter is in the wait-for-trigger state.
•You can also trigger the multimeter from the GPIB interface by
sending the IEEE-488 Group Execute Trigger (GET) message.
The multimeter must be in the wait-for-trigger state. The following
statement shows how to send a GET using BASIC.
