"Single" "Trace&Statistics" mode only. This setting disables continuous trigger-
ing so that only one trigger event at a time is executed. To enable trig-
gering again, press the (DEL/1TRIG) key. The symbol
appears
in the display (see
​
chapter 4.2.7, "Trigger sequence control" ,
on page 89).
"Normal" Continuous triggering with regular trigger events.
"Auto" "Trace&Statistics" mode only. This setting automatically starts a mea-
surement if no trigger event has occurred after 300 ms.

Source
Selects the trigger source for the selected sensor. The measured internal signal ("Inter-
nal") or an external signal is available for triggering. The external trigger signal is either
input at the TRIG IN / OUT2 connector at the rear of the instrument ("External") or it is
supplied by another power sensor which must be configured as a trigger master ("Int.
Master").
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 measured
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 153.
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 mas-
ter and set to internal triggering. Any previously defined trigger master
is disabled and an external trigger signal at the TRIG IN / OUT2 con-
nector is ignored.
The trigger master is used as the external trigger source for all other
sensors.
