Trigger source
Description
Remote commands to initiate the measurement
"Internal"
Uses the input signal as trigger signal.
TRIGger<Measurement>[:IMMediate]
"Internal
A" , "Inter-
nal
B" , "Internal
C" ,
"Internal
D"
Receives the trigger signal from the trigger mas-
ter. The trigger master is the sensor connected to
port
A, B, C, or D. See
-
"External"
Uses the external trigger signal that is supplied at
the Trig In / Out
2 connector. See
TRIGger<Measurement>[:IMMediate]
"External
2"
Requires a power sensor with a trigger input/
output.
Uses the external trigger signal that is supplied at
the trigger input/output of the power sensor.
TRIGger<Measurement>[:IMMediate]
"Sensor Check
Source"
Requires the sensor check source (R&S NRX-B1)
option.
If enabled, the sensor check source (R&S NRX-
B1) sends trigger signals using the internal trigger
bus. See
TRIGger<Measurement>[:IMMediate]
"Bus (*TRG)"
Waits for a trigger event. Press [1Trig] to trigger
the measurement.
Depending on the sensor type, the trigger is exe-
cuted by the trigger bus or by remote command.
See the user manual of the power sensor for
details.

Dropout Time
The dropout time is useful when dealing with signals with several active slots, for
example GSM signals, see
. When measuring in sync with the signal, a trig-
ger event is to be produced at A, but not at B or C.
