To connect an R&S
NRP power sensor
The following procedure describes how to connect R&S
SMW to an R&S
NRP power
sensor as alignment source. Also, it describes how to connect the power sensor and a
directional coupler. The R&S
SMW is switched on and connected to power.
For prerequisites of the power sensor, see
1.
NOTICE!
Cable selection. Use all cables delivered with the R&S
NRP power sen-
sor. Other connections can require additional cables.
For the control connection, use the cable R&S
NRP-ZK6 as delivered with the
R&S
NRP power sensor.
For the RF connection, use a high-quality cable.
See "Cable selection and electromagnetic interference (EMI)" in the R&S
SMW
Getting Started.
2. Insert the host connector of the power sensor into the "SENSOR" of the
R&S
SMW.
3. Establish the RF connection between power sensor and directional coupler.
a) Ensure that the RF connector of the directional coupler is compatible with the
RF connector of the power sensor.
b) Inspect both RF connectors carefully. Look for metal particles, contaminants
and defects.
If either RF connector is damaged, do not proceed, because the risk of damag-
ing the mating connector is too high.
c) Insert the RF connector of the power sensor straight into the RF output of the
directional coupler. Take care not to tilt it.
The table below provides an overview of the connections.
