7 Replacing an R&S NRP‑Zxx with an R&S
NRPxxP
The R&S NRPxxP power sensors are compatible with the R&S NRP‑Zxx series of
power sensors.
R&S NRPxx power sensor Replaces R&S NRP‑Zxx power sensor
R&S NRP18P R&S NRP-Z81
R&S NRP40P R&S NRP-Z85
R&S NRP50P R&S NRP-Z86
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 (version 4.20 or higher).
For using the power sensors with base units, signal generators, spectrum analyzers or
other Rohde & Schwarz instruments, install the latest firmware version.
7.1 Important difference
After powering the R&S NRPxxP, the firmware is loaded. Because the USB power sen-
sors 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.
7.2 Prerequisites
Install the R&S NRP Toolkit version 4.20 or higher, see Chapter 5.1, "R&S NRP Tool-
kit", on page 20.
The new version of the R&S NRP Toolkit is compatible with both the R&S NRP‑Zxx
and the R&S NRPxxP so that its installation does not affect the usage of the
R&S NRP‑Zxx.
After the new version of the R&S NRP Toolkit is installed, you can connect the R&S
NRPxxP to the computer and use it with Rohde & Schwarz software applications or
your own programs. For information on Rohde & Schwarz software applications, see
the release notes and the manual of the software application.
