Used to connect the power sensor to a device under test (DUT) or a signal gener-
ator.
Caused by their different frequency ranges, the R&S NRP
‑
Z power sensors have
different RF connectors. Also, for maximal measurement accuracy, the RF con-
nector must be tightened using a torque wrench with a specific nominal torque.
Refer to the operating manual of your R&S NRP
‑
Z power sensor for information
on your connector and the allowed nominal torque.

Z Power Sensors
When connecting the R&S
NRP-Z27/-Z28/-Z37/-Z98 sensors, there are
additional requirements to fulfill. Refer to the operating manual of the corre-
sponding sensor for a description on how to connect it.

Risk of damage to the center pin of the RF connector
When connecting the power sensor, always rotate only the union nut of the
RF connector. Do not rotate the sensor itself to avoid damage the center pin
of the connector.
1. Refer to the operating manual of your R&S NRP
‑
Z power sensor to find out
what kind of RF connector your sensor has and the recommended nominal
torque.
2. Insert the RF connector of the attenuator straight into the RF output of your
DUT. Do not tilt it.
