Connecting the sensor
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, 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.
Because the power sensor R&S NRP-Z27/-Z37 has a maximum current capacity of 100 mA and is
therefore classified as a low-power device, it can be supplied with current from any stationary PC,
laptop or notebook in the bus-powered mode.
