[:IMMediate]
TRIGger[:IMMediate]
causes a trigger to occur immediately provided the
multimeter is in the wait-for-trigger state (see the
INITiate
subsystem). The trigger
source must be
TRIGger:SOURce BUS
or
TRIGger:SOURce HOLD
.
Comments
•
The
[:IMMediate]
parameter is optional. Both of the following command
statements are valid:
TRIG:IMM
or
TRIG
•
When the
TRIG:IMM
command is executed, the readings are stored in
mainframe/command module memory. Use
FETCh?
to place the readings in the
output buffer.
•
The
TRIGger:SOURce BUS
or
TRIGger:SOURce HOLD
commands remain in
effect after the
TRIG:IMM
command is executed.

:SOURce
TRIGger:SOURce <
source
>
configures the trigger system to respond to the
specified source. The following sources are available:
BUS
: Group Execute Trigger (
GET
) bus command or
*TRG
common command.
EXT:
The multimeter’s External Trigger BNC connector.
HOLD
: Suspend triggering. Only the
TRIGger:IMMediate
command will trigger the
multimeter.
IMMediate
: The trigger system is always true (continuous triggering). The only
valid trigger sources with
IMMediate
are
TRIGger:SOURce BUS
and
TRIGger:SOURce HOLD
.
TTLTrg0 - TTLTrg7
: Trigger source is VXIbus trigger line 0 through 7. These trigger
sources are available with the HP E1411B multimeter only.
