Basics on Power Sensors
For precise power measurement, up to 4 power sensors can be connected to the
instrument via the power sensor interface (on the front panel) or the USB connectors.
Both manual operation and remote control are supported.
For a detailed list of supported sensors, see the data sheet.
Power sensors can also be used to trigger a measurement at a specified power level,
e.g. from a signal generator (see

Using the power sensor with several applications
The power sensor cannot be used from the R&S
FSMR3 firmware and the R&S Power
Viewer Plus (virtual power meter for displaying results of the R&S NRP power sensors)
simultaneously.
Result display
The results of the power sensor measurements are displayed in the marker table. For
each power sensor, a row is inserted. The sensor index is indicated in the "Type" col-
umn.
Using a Power Sensor as an External Power Trigger
Power sensors can be used to trigger a measurement at a specified power level, e.g.
from a signal generator. For a list of supported power sensors see the data sheet.
With the R&S
FSMR3, the power sensors can be connected to the "Power Sensor"
interface directly, and no further cables are required. They can then be configured as
an external power sensor trigger.
