Operation with other Rohde & Schwarz 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.
