8 Replacing an R&S NRP‑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 Chapter 5.1, "R&S NRP Toolkit",
on page 31.
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.
