R&S
FSW-K7
RF Power ← Trigger Source
Defines triggering of the measurement via signals which are outside the displayed
measurement range.
For this purpose, the instrument uses a level detector at the first intermediate fre-
quency.
The input signal must be in the frequency range between 500 MHz and 8 GHz.
The resulting trigger level at the RF input depends on the RF attenuation and preampli-
fication. For details on available trigger levels, see the instrument's data sheet.
Note: If the input signal contains frequencies outside of this range (e.g. for fullspan
measurements), the sweep may be aborted. A message indicating the allowed input
frequencies is displayed in the status bar.
A "Trigger Offset", "Trigger Polarity" and "Trigger Holdoff" (to improve the trigger stabil-
ity) can be defined for the RF trigger, but no "Hysteresis".
This trigger source is not available for input from the optional Digital Baseband Inter-
face or the optional Analog Baseband Interface . If the trigger source "RF Power" is
selected and digital I/Q or analog baseband input is activated, the trigger source is
automatically switched to "Free Run".
Remote command:
TRIG:SOUR RFP, see
Power Sensor ← Trigger Source
Uses an external power sensor as a trigger source. This option is only available if a
power sensor is connected and configured.
Note: For Rohde & Schwarz power sensors, the "Gate Mode" Lvl is not supported. The
signal sent by these sensors merely reflects the instant the level is first exceeded,
rather than a time period. However, only time periods can be used for gating in level
mode. Thus, the trigger impulse from the sensors is not long enough for a fully gated
measurement; the measurement cannot be completed.
Remote command:
TRIG:SOUR PSE, see

Trigger Level

Defines the trigger level for the specified trigger source.
For details on supported trigger levels, see the data sheet.
