Note: In addition to using an internal or external trigger source, a trigger event can be
forced using the DEL/1TRIG
hardkey, see chapter 4.2.7, "Trigger sequence control",
on page 89.
"Internal"
The trigger event for the selected sensor is derived from the mea-
sured signal.
"External"
The trigger event for the selected sensor is derived from the trigger
bus. The trigger signal on the trigger bus is either input at the TRIG
IN / OUT2
connector at the rear of the instrument or it is provided by
another sensor.
If the trigger signal is input at the TRIG IN / OUT2 connector, the con-
nector must be configured for "Trigger In" in the "System" menu, see
chapter 4.7.2.2, "I/O 2 interface", on page 155.
If the trigger signal is provided by another sensor, this sensor must be
configured as trigger master, see below, "Int. Master".
"Int. Master"
The selected power sensor is automatically configured as trigger
master and set to internal triggering. Any previously defined trigger
master is disabled and an external trigger signal at the
TRIG IN /
OUT2 connector is ignored.
The trigger master is used as the external trigger source for all other
sensors.
Remote command:
TRIGger:
ALL:SOURce
on page 334
Slope
Sets the polarity of the active slope of the externally or internally applied trigger signal,
see Source.
" Positive"
The rising edge of the trigger signal is active.
"Negative"
The falling edge of the trigger signal is active.
Remote command:
TRIGger<[1]..4>:SLOPe
on page 334
Level
Sets the trigger threshold for internal triggering. Depending on the slope polarity, a ris-
ing or a falling edge will execute a trigger event when crossing the threshold. Modifica-
tions of the level are immediately effective (see chapter 3.5, "Dialog boxes and their
controls", on page 53).
Remote command:
TRIGger:
ALL:LEVel on page 333

Trigger dialog box (2)
The second page covers the parameters for defining a trigger delay and a dropout time
to prevent accidental triggering.
