:EXTernal[:TRIGger]:SOURce?
:EXTernal[:TRIGger][:OUTPut] <0|1|OFF|ON>
:EXTernal[:TRIGger][:OUTPut]?
These commands select and enable external triggers. Two possible
source are available: the built-in source available at the rear-panel mini-
DIN connector or the EI/CC lines in a 44474A DIO Module. For
additional information about external triggering see “Using External
Triggering” on page 93.
The slot parameter in the command sets the location of the external
trigger lines. The built-in trigger lines are on slot “0”. If a 44474A is
installed, slot can be set to the corresponding slot number. After power
on or a reset (*RST) command, the slot is set to “0”.
The CONFigure:EXTernal:TRIGger:SOURce? query returns a
number indicating the external trigger source.
The CONFigure:EXTernal:TRIGger:OUTPut command enables or
disables the external trigger out pulse. This pulse is output after a
channel is closed during a scan operation when enabled. The output
pulse timing may be delayed after the channel is closed if the
ROUTe:CHANnel:DELay command has been set for the channel. After
power on or a reset (*RST) command is received, the output pulse is
disabled (OFF).
The CONFigure:EXTernal:TRIGger:OUTPut? query returns either a
“0” (disabled) or “1” (enabled) indicating the status of the external trigger
output.
