R&S FSW-K7
Manual operation:
TRIGger[:SEQuence]:OSCilloscope:COUPling <CoupType>
Configures the coupling of the external trigger to the oscilloscope.
Parameters:
<CoupType>
Manual operation:
TRIGger[:SEQuence]:LEVel:RFPower <TriggerLevel>
This command defines the power level the RF input must exceed to cause a trigger
event. Note that any RF attenuation or preamplification is considered when the trigger
level is analyzed. If defined, a reference level offset is also considered.
The input signal must be between 500 MHz and 8 GHz.
Parameters:
<TriggerLevel>
Example:
Manual operation:
TRIGger[:SEQuence]:LEVel:AM:RELative <Level>
The command sets the level when AM-modulated signals are used as trigger source.
For triggering to be successful, the measurement time must cover at least 5 periods of
the audio signal.
Parameters:
<Level>

Coupling type
DC
Direct connection with 50 Ω termination, passes both DC and
AC components of the trigger signal.
CDLimit
Direct connection with 1 MΩ termination, passes both DC and
AC components of the trigger signal.
AC
Connection through capacitor, removes unwanted DC and very
low-frequency components.
*RST: DC
See "Coupling" on page 102
For details on available trigger levels and trigger bandwidths see
the data sheet.
*RST: -20 dBm
TRIG:LEV:RFP -30dBm
See "Trigger Level" on page 101
Range: -100 to +100
*RST: 0 %
Default unit: %
TRIG:LEV:AM:REL -20 %
Sets the AM trigger threshold to -20 %
