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 power sensor contains components which can be destroyed by electrostatic
discharges. To prevent this happening, never touch the inner conductor of the RF
connector and never open the power sensor.
NOTICE
To prevent EMI, the power 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 power
sensor.

Unpacking the sensor
Remove the 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 sensor is to be shipped or transported at a later date.
Connecting the sensor
Caused by their different frequency ranges, the R&S NRP-Z81/85/86 power sensors have different RF
connectors. In this context, the following sections will refer to Table 1-1:
Table 1-1 RF connectors of R&S NRP-Z81/85/86 power sensors

Operation with the R&S NRP/NRP2 power meter R&S NRP-Z81/-Z85/-Z86
Operation with the R&S NRP/NRP2 power meter
Connecting the power sensor
The power sensor can be connected to the R&S NRP/NRP2 base unit when it is in operation. The
multiple circular plug-in connector must be inserted, red marking upwards, into one of the
R&S NRP/NRP2 base unit’s sensor connectors. When the power sensor is connected, it is detected by
the R&S NRP/NRP2 base unit and initialized.
See Table 1-1 for the type of male RF connector a certain power sensor has and which female
connectors it mates with. Using light pressure, and keeping the male connector perpendicular, insert it
into the female connector and tighten the locking nut (right-hand thread). 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 that corresponds with the
tightening torque shown in Table 1-1.
PC control
Hardware and software requirements
The following requirements must be met if the power sensor is to be controlled by a PC via an interface
adapter:
The PC must have a USB port.
Either Microsoft Windows XP (32 Bit), Microsoft Windows Vista (32 or 64 Bit), Microsoft Windows 7
(32 or 64 Bit), or x86 Linux (with kernel 2.6.8 oder more recent) must be installed as the operating
system of the PC. 64-bit versions of Microsoft Windows XP are not supported. Operation with older
versions of Microsoft Windows with USB support (especially Microsoft Windows 2000) is normally
possible but cannot be guaranteed.
The USB device drivers in the supplied NRP Toolkit software package must be installed.
If these requirements are met, the power sensor can be controlled using a suitable application program
such as the NrpFlashup program contained in the Microsoft Windows version of the NRP Toolkit
(includes the modules Power Viewer, USB Terminal, Firmware Update and Update S-Parameters).
When you insert the CD-ROM supplied with the R&S NRP power sensor, the NRP Toolkit is
automatically installed on your PC. The rest of the procedure is self-explanatory.
The power sensor can be powered in two ways:
Self-powered from a separate power supply via the Active USB Adapter R&S NRP-Z3 or the
Sensor Hub R&S NRP-Z5.
Bus-powered from the PC or a USB hub with its own power supply (self-powered hub) via the
Active USB Adapter R&S NRP-Z3 or via the Passive USB Adapter R&S NRP-Z4.
As the power sensor is a high-power device, there is no guarantee that it can be powered from all types
of laptop or notebook in the bus-powered mode. To be sure, you should determine the current at the
USB connectors beforehand:

Connecting the sensor to the DUT
See Table 1-1 for the type of male RF connector a certain power sensor has and which female
connectors it mates with. Using light pressure, and keeping the male connector perpendicular, insert it
into the female connector and tighten the locking nut (right-hand thread). 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 that corresponds with the
tightening torque shown in Table 1-1.
Operation via the Active USB Adapter R&S NRP-Z3
Fig. 1-3 shows the configuration with the Active USB Adapter R&S NRP-Z3, which also makes it
possible to feed in a trigger signal for the Timeslot and Trace modes. The order in which the cables are
connected is not critical.
Fig. 1-3 Configuration with Active USB Adapter R&S NRP-Z3
The plug-in power supply for the R&S NRP-Z3 can be powered from a single-phase AC source with a
nominal voltage range of 100 V to 240 V and a nominal frequency between 50 Hz and 60 Hz. The plugin power supply autosets to the applied AC voltage. No manual voltage selection is required.
The plug-in power supply comes with four primary adapters for Europe, the UK, the USA and Australia.
No tools of any kind are required to change the primary adapter. The adapter is pulled out manually and
another adapter inserted until it locks (Fig. 1-4).

NOTICE
The plug-in power supply is not intended for outdoor use.
Keep within the temperature range of 0°C to 50°C.
If there is any condensation on the plug-in power supply, dry it off before connecting it to
the AC supply.
Fig. 1-4 Changing the primary adapter
The plug-in power supply is short-circuit-proof and has an internal fuse. It is not possible to replace this
fuse or open the plug-in power supply.
Operation via the R&S NRP-Z5 Sensor Hub
The R&S NRP-Z5 sensor hub allows up to four power sensors to be operated on one PC. It combines
the following functions:
4-port USB 2.0 hub
Power supply
Through-wired trigger bus
Trigger input and trigger output via BNC sockets
Equipment Supplied and Alternative Accessories
The following equipment is supplied:
Sensor hub
External power supply
Power cable
USB cable
Instead of the supplied, 2 m long USB cable, it is possible to use any other USB-2.0-certified cable
(USB connector type A to USB connector type B) with a maximum length of 5 m. If a locking connection
is required at the instrument end, it is also possible to use the passive R&S NRP-Z4 interface adapter
instead of a standard USB cable.
As an alternative to the supplied external power supply, power can also be supplied using a DC voltage
source with an output voltage of 12 V to 24 V and a power output of at least 24 W. Make sure that the
polarity is correct (positive pole inside, negative pole outside). The alternative DC voltage source must
be in the same building as the R&S NRP-Z5 and must be connected to the latter via a cable with a
maximum length of 30 m. Power must not be supplied from a low-voltage supply system.
The supplied external power supply is short-circuit-proof and is also protected by an internal fuse. It is
not possible to change the fuse or open the unit.

Test Setup
Fig. 1-8 shows a typical test setup:
The sequence in which the cables are connected is not important.
As already mentioned in section Ports and LEDs, the R&S NRP-Z4 passive interface adapter can also
be used as an alternative to a standard USB cable for connecting to the PC. This adapter is connected
to the R&S Instrument port. Simultaneous operation at two USB hosts is not possible as the USB host
connected to the R&S Instrument port always has priority.
It is possible to cascade several R&S NRP-Z5 sensor hubs by connecting the R&S Instrument port of
an R&S NRP-Z5 to one of the sensor ports of another R&S NRP-Z5. However, external triggering and
the use of the Trigger Master function are then not possible. Instead, it is recommended to connect all
R&S NRP-Z5 hubs individually to the USB host or to an interposed USB hub, and to feed the external
trigger signal to all R&S NRP-Z5 hubs via their trigger inputs; or to forward the external trigger signal
from the trigger output of the R&S NRP-Z5 to which the Trigger Master is connected to the trigger
inputs of the other R&S NRP-Z5 hubs.

Troubleshooting
A frequent problem, especially in the case of operation under Microsoft Windows XP, is that the
R&S NRP-Z5 fails to respond after a power sensor connected to the R&S NRP-Z5 is disconnected and
reconnected. It is then necessary to restart the PC.
This problem is not specific to the R&S NRP-Z5, but occurs with all USB hubs. You can try to eliminate
the problem by switching off the Selective Suspend for the USB port of the PC on which the R&S NRPZ5 is operated. The following step-by-step description is based on an English version of Windows XP:
1. Connect the R&S NRP-Z5 and put it into operation. Connect at least one power sensor.
2. Start the Device Manager and change the view by selecting View - Devices by connection (Fig.
1-9).
Fig. 1-9 Changing the view in Device Manager
3. Now identify the USB root hub on which the R&S NRP-Z5 is operated. To do so, expand the
hierarchical display of the PC components, as shown in Fig. 1-10. Under PCI bus, find the USB
host controller to whose root hub the R&S NRP-Z5 is connected. The R&S NRP-Z5 is shown as the
Generic USB Hub. It can be distinguished from other USB hubs by the power sensor connected to
it.

4. Double-clicking USB Root Hub opens the USB Root Hub Properties dialog box. Select the Power
Management tab. Remove the check mark next to Allow the computer to turn off this device to
save power and confirm this with OK.

Operation with other R&S test instruments
Hardware and software requirements
Many Rohde & Schwarz test instruments allow power measurements using power sensors of the
R&S NRP-Zxx series. The power sensors are generally connected to the USB ports of the test
instrument via one of the two interface adapters, R&S NRP-Z3 or R&S NRP-Z4, or the Sensor Hub
R&S NRP-Z5. On some instruments, such as the R&S SMU signal generator, there is also an
R&S NRP sensor connector available for a direct connection. The R&S NRP-Z5 can be hooked up to
this connector via an extension cable R&S NRP-Z2 (Model .03, .05, or .15). For that purpose, the
R&S Instrument connector of the R&S NRP-Z5 is used.

R&S NRP-Z81/-Z85/-Z86 Overview
2 Virtual Power Meter
You will find the NrpFlashup program for controlling sensors with a PC under Windows™ on the
CD-ROM that accompanies the sensor. The program comprises several modules which can be started
centrally via the Windows™ start-menu entry NRP Toolkit.
This section describes the Power Viewer program module. This is a virtual power meter which only
uses a cut-down set of the sensor’s functions. This means that after an extremely brief familiarization
period, the user can measure the average power of modulated signals.
The other modules in NrpFlashup are described in Chapter 3 of the operating manual (Terminal and
Update S-Parameters modules) or in the service manual (Firmware Update module).
Overview
Start the virtual power meter using the NRP Toolkit – Power Viewer start-menu entry. The Power
Viewer program window is displayed (Fig. 2-1).
Fig. 2-1 Power Viewer – virtual power meter
The result display occupies most of the program window. The result, unit and additional sensor status
information are displayed. The serial number of the sensor is displayed in the bottom right. The program
window also contains animated buttons and entry fields (see Table 2-1 and Table 2-2).

module simplifies the most frequently used function of a power meter – measuring the average power of
an RF signal of almost any modulation. Other program modules are also part of the supplied equipment
and can be selected in the Start menu:
• Power Viewer: A detailed description of this virtual power meter module is provided in
section 2.
• Terminal: Program module for sending commands and command sequences to the
sensor and for displaying measurement results, status information and
other data from the sensor
• Firmware Update: Program module for updating the sensor firmware
• Update S-Parameters: Program module for loading an s-parameter table into the sensor
Program module “Terminal”
Main control elements
With the USB terminal, commands and command sequences can be sent to the sensor in two different
ways:
• Commands are entered in the Input field (Fig. 3-1). Consecutive commands can be entered as
separate lines, one below the other. The buttons associated with the Input field are described in
Table 3-1.
• Commands or command sequences are stored in command files. Command files are created with a
text editor, for instance, and then stored. They can be called as often as required (Fig. 3-2). The
buttons of the Command File field are described in Table 3-2.
