Using a Single
Trigger
The multimeter can be internally triggered with a single trigger signal. This
signal is issued with the
TRIGger[:IMMediate] command:
Before a single trigger can be sent, however, the trigger source must be set
to HOLD and the multimeter must be in the wait-for-trigger state. These
conditions are shown in the following program which shows how a single
trigger can be used.
Example:
Measurements with a
Single Trigger
When TRIG is executed, the multimeter makes 10 DC voltage
measurements and stores them in mainframe memory. The
FETCH?
command retrieves the readings.
10 !Configure the stand-alone multimeter for DC voltage measurements.
20 !Suspend triggering and set 10 measurements to be taken when the single
30 !trigger is received.
40 CONF:VOLT:DC
50 TRIG:SOUR HOLD
60 SAMP:COUN 10
70 !
Place the multimeter in the wait-for-trigger state and issue a single trigger.
80 !Fetch the readings from memory.
90 INIT
100 TRIG
110 FETCH?
Aborting a
Measurement
When the multimeter is in the wait-for-trigger state it can be returned to the
idle state before the trigger signal is received. This is done with the
ABORt
command.
Trigger sources which allow the
ABORt command to return the multimeter
to the idle state are
TRIGger:SOURce BUS and TRIGger:SOURce HOLD.
The next two examples show how
ABORt works.
