1 Putting into Operation
NOTICE
Follow the instructions below precisely to prevent damage to the power sensor
–
particularly when you are putting it into operation for the first time.
The collective designation "R&S NRP-Z5x", where the x stands for any digit, refers to a family of
thermal power sensors. If formulations apply to all power sensors of the family, the collective
designation is employed. Yet, if formulations only apply to certain power sensors, their exact type
designations are employed.
Unpacking the power sensor
Remove the power sensor from its packing and check that nothing is missing. Inspect all items for
damage. If you discover any damage, inform the carrier responsible immediately and keep the packing
to support any claims for compensation.
It is also best to use the original packing if the power sensor is to be shipped or transported at a later
date.
The power sensor contains components which can be destroyed by electrostatic
discharges. To prevent this from happening, never touch the inner conductor of the RF
connector and never open the power sensor.
Connecting the power sensor
NOTICE
To prevent EMI, the sensor must never be operated with its enclosure wholly or partially
removed. Only use shielded cables that meet the relevant EMC standards.
Never exceed the maximum RF power limit. Even brief overloads can destroy the sensor.
The R&S NRP-Z5x power sensors have a new type of ball-bearing RF connector. Since
the friction with this design is considerably less than with conventional RF connectors, a
reproducible connection is ensured even at relatively low torques. Make sure that the
sensor body can still be turned opposite the mating part. Do not try to prevent this by
increasing the torque above the permissible value or by tightening the connection by
turning the sensor body.
Caused by their different frequency ranges, the R&S NRP-Z5x power sensors have different RF
connectors. In this context, the following sections will refer to Table 1-1:
