R&S NRP-Z27/-Z37 Safety Information
1169.3870.12 I E-1
Safety Information
Safety information is part of the product documentation. It warns you of potential dangers and gives
instructions on how to prevent personal injury or damage caused by dangerous situations. Safety
information is provided as follows:
•In the Getting Started manual, Chapter 1.1 “Safety instructions”. The same information is provided in
many languages as printed "Safety Instructions". Both documents are delivered with the power
sensor.
•Throughout the documentation, safety instructions are provided when you need to take care during
setup or operation.

R&S NRP-Z27/-Z37 Supplement
1169.3870.12 Supplement 1 E-1
Operation of the Power Sensor Module R&S NRP-Z27/-Z37
on the R&S NRP base unit
The power sensor module supplied with this manual has firmware version 01.61 or later. To operate it
on the R&S NRP base unit, all software components installed on the base unit must have version num-
ber 02.00 or later. If you want to use the distortion compensation (command group: SENSe:RGAMma,
see page 6-12), the 'Main Program' must have at least version number 3.24.
The version numbers of the software components can be read out under the menu item 'System Info', in
the lines 'Main Program', 'Bootloader' and 'Keybd. Ctrl'. For firmware versions earlier than 02.00, the
menu item 'System Info' can be found in the File menu; otherwise, in the System menu.

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.
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 sensor
NOTICE
To prevent EMI, the power sensor module 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
integrated power sensor.
To prevent erroneous measurements, always terminate the RF output of the power sensor
module (at the cable end) with a matched load or matched measuring instrument input.
In many cases, the RF connector only requires manual tightening. However, for maximal
measurement accuracy, the RF connector must be tightened using a torque wrench with a
nominal torque of 1.36 Nm (12" lbs.) for the N connector of the R&S NRP-Z27, or 0.9 Nm
(8" lbs.) for the 3.5 mm connector of both power sensor modules.

Do not apply excessive mechanical force to the RF
connectors of the R&S NRP-Z27/-Z37 and DUT!
