Using the power sensor with several applications
The power sensor cannot be used from the R&S FSW 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 FSW, the power sensors can be connected to the "Power Sensor" inter-
face directly, and no further cables are required. They can then be configured as an
external power sensor trigger.
Figure 8-3: Connecting a power sensor using the POWER SENSOR interface
The R&S FSW receives an external trigger signal when the defined trigger level is
measured by the power sensor. Power measurement results are provided as usual.
The "Gate Mode" Level is not supported for R&S power sensors. 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 trig-
ger impulse from the sensors is not long enough for a fully gated measurement; the
measurement cannot be completed. For details on gating see
Chapter 8.6.2.1, "Gated
Measurements" , on page 488.
For details see "How to Configure a Power Sensor as an External (PSE) Trigger"
on page 381.
