156 Multimeter Command Reference Chapter 3
TRIGger
The TRIGger command subsystem controls the behavior of the trigger system. The
subsystem can control:
The number of triggers to occur before the multimeter returns to the idle state
(
TRIGger:COUNt).
The delay between trigger and measurement (TRIGger:DELay).
The source of the trigger (TRIGger:SOURce).

:COUNt
TRIGger:COUNt <number> sets the number of triggers to be issued.
Parameters
Comments MIN selects 1 trigger. MAX selects 50,000 triggers.
If MAX or 50,000 is specified for the number parameter, the command will be
accepted. If you initiate measurements with an
INITiate command, an
“Insufficient memory” error occurs to show that this generates too many
readings to store in memory. However, you can use the
READ? command to
return the readings to the output buffer and retrieve them with your controller.
The
READ? command is a combined INITiate and FETCh? command.
CONFigure and MEASure set the trigger count to 1.
*RST Condition: TRIG:COUN 1
Example Set the Trigger Count
CONF:VOLT:DC
Function: DC voltage.
TRIG:SOUR EXT
Trigger source is “Trig” BNC on multimeter
front panel.
TRIG:COUN 10
Multimeter will accept 10 external triggers
(one measurement is taken with each trigger).
READ?
Place multimeter in wait-for-trigger state;
make measurement when external trigger is
received; send readings to output buffer.
enter statement
Enter readings into computer.
