[: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.
• Related Commands: FETCh?, INITiate, TRIGger:SOURce
Example Sending an Immediate Trigger
CONF:VOLT:DC !Function: DC voltage; stand-alone
multimeter.
TRIG:SOUR HOLD !Suspend triggering.
INIT !Place multimeter in wait-for-trigger state;
store reading in memory when trigger is
received.
TRIG !Trigger the multimeter.
FETC? !Place reading in output buffer.
enter statement !Enter reading into computer.
: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.
