Zxx with an R&S
NRPxxS(N)
The R&S NRPxxS(N) power sensors are compatible with the R&S
NRP

Zxx series of
power sensors.

To use the new power sensors, it can be required to update the drivers. For computer-
based software applications (R&S
NRPV and R&S
Power Viewer), install the latest
R&S
NRP Toolkit (V
4.20 or higher).
For using the sensors with base units, signal generators, spectrum analyzers or other
Rohde & Schwarz instruments, install the latest firmware version.
8.1
Important difference
After powering the R&S NRPxxS(N) , the firmware is loaded. Because the USB power
sensors are plug-and-play devices, the drivers are loaded after enumeration in the host
system. For the R&S
NRP
‑
Zxx power sensors, the whole process takes 4
s to 5
s. For
USB power sensors, the process can take up to 8
s.
Otherwise, the R&S
NRP
‑
Zxx power sensors and the USB power sensors are compati-
ble as far as possible.
8.2
Prerequisites
Install the R&S
NRP Toolkit V
4.20 or higher, see
The new version of the R&S
NRP Toolkit is compatible with both the R&S
NRP
‑
Zxx
and the R&S NRPxxS(N) so that its installation does not affect the usage of the
R&S
NRP
‑
Zxx.
