R&S®NRP-Z Power Sensors
For operation with R&S®NRX base unit or via USB on a Laptop/PC
The R&S®NRP family from Rohde & Schwarz is the only power sensor portfolio worldwide in which every sensor can be connected to a laptop/PC via USB.
The sensors function as independent measuring instruments and are completely characterized over frequency, level and temperature. Only a display unit, such as the R&S®NRX base unit, a laptop/PC or supported Rohde & Schwarz instrument, is required to view measurement results.
The robust USB protocol handles communications between power sensor and display unit, eliminating measurement errors that could result from transferring measurement data. The USB interface also allows users to operate all sensors directly on a PC via the R&S®NRP-Z4 adapter cable.
- Continuous average mode: reliable average power measurements on CW and modulated signals; supported by all R&S®NRP power sensors
- Burst average mode: burst average power measurements; sensors automatically detect start and end of the burst
- Trace mode: display of the envelope power versus time
- Timeslot mode: timeslot average power measurements on TDMA-based signals (e.g. GSM/EDGE, DECT)
- Time gate mode: average power measurements in up to four independent gates with individual time position and length
- Statistic mode: display of CCDF, CDF and PDF for analyzing noise-like CDMA (3GPP) and OFDM (LTE) signals

The R&S®NRP power sensors are immediately ready for use. Contrary to conventional power sensors, no calibration is required prior to making measurements since the sensors are completely characterized over frequency, level and temperature and feature long-term stability. All calibration data is stored in the sensor. The sensors function as independent measuring instruments and can be operated on the R&S®NRX base unit, a laptop/PC or other instruments from Rohde & Schwarz (e.g. signal generators). Usually, no zeroing is required. Users can simply plug in the sensor and start measuring.
Even complex test setups represent no challenge for the R&S®NRP family of power sensors. Interfering effects like cable losses and reflections can be compensated using offset, S‑parameter and Γ correction. Offset correction helps to take into account non-frequency-dependent attenuation. S‑parameter correction is used to mathematically shift the reference plane directly to the device under test (DUT) by taking into account the S-parameters for any component connected upstream. Γ correction makes it easy to compensate for the effects of impedance mismatch.

With fixed noise averaging (an enhanced auto averaging function) any measurement can be optimized with respect to measurement time and accuracy. The averaging filter is dynamically set to the optimum averaging value to achieve user-definable maximum noise content. This helps to achieve the shortest possible measurement time and the maximum production throughput with a specified accuracy, and to simplify the programming of remotely controlled measurement sequences.
The R&S®NRX base unit and all R&S®NRP power sensors are easily integrated into automated test setups with the available drivers (LabView, LabWindows/CVI and VXI). The R&S®NRX base unit can be remotely controlled via GPIB, LAN or USB.
The power sensors can be operated either on an R&S®NRX base unit or directly on a laptop/PC. They are also supported by numerous signal generators, signal analyzers, spectrum analyzers and network analyzers from Rohde & Schwarz.
The R&S®NRP-Z4 passive USB adapter cable is all that is needed to connect the sensors to a laptop/PC. To measure very low power level, an external trigger signal is required. This signal can be conveniently supplied via the trigger input of the R&S®NRP-Z3 active USB adapter cable or the R&S®NRP-Z5 sensor hub.
The sensor hub allows users to connect up to four sensors to a laptop/PC without additional adapters and to simultaneously start the measurements using an external trigger signal.
