Sweep Count
Specifies the number of sweeps to be performed for Spectrum ACP/ACPR and Spec-
trum Mask measurements.
Remote command:
[SENSe:]SWEep:COUNt on page 200
Trigger Mode
Sets the source of the trigger for the data capture process of the measurement.
"Free Run"
The measurement sweep starts immediately.
"External"
The measurement sweep starts if the external trigger signal meets or
exceeds the external trigger level (a fixed value that cannot be
altered) at the input connector EXT TRIGGER/GATE IN on the rear
panel.
"IF Power"
The measurement sweep starts when the signal power meets or
exceeds the specified power trigger level. This trigger mode is not
available for Spectrum Mask measurements in ETSI standard. If it is
set and then the Spectrum Mask measurement in ETSI standard is
selected, it automatically changes to "Free Run".
"RF Power"
The next measurement is triggered by the first intermediate frequency
of the RF signal.
"Power Sensor"
The next measurement is triggered by the external power sensor
(requires R&S FSV-K9 option).
"External Using FS-Z11"
If activated, the next measurement is triggered by the signal at the
external trigger input connected to the R&S
®
FS-Z11 trigger unit. This
allows for data to be captured from all connected analyzers synchro-
nously for MIMO measurements.
For details see chapter 3.6.1, "Trigger Synchronization Using an
R&S
®
FS-Z11 Trigger Unit", on page 37.
Remote command:
TRIGger[:SEQuence]:MODE on page 218
Trigger Offset
Specifies the time offset between the trigger signal and the start of the sweep. A nega-
tive value indicates a pre-trigger. This field is not available in the "Free Run" trigger
mode.
Remote command:
TRIGger[:SEQuence]:HOLDoff on page 217
Trigger Holdoff
Defines the value for the trigger holdoff. The holdoff value in s is the time which must
pass before triggering, in case another trigger event happens.
