MWC 2018: Rohde & Schwarz will present R&S NRQ6, the first high-precision frequency-selective power sensor

The R&S NRQ6 combines the accuracy of a power meter with the dynamic range of a spectrum analyzer. It is the only power sensor on the market to perform extremely precise and fast measurements down to –130 dBm. These features, which are enhanced by the sensor’s excellent linearity, make it possible to calibrate transmitter output power with a single device.

The power sensor R&S NRQ6 is controlled via a LAN web interface.

The innovative R&S NRQ6 power sensor operates in a frequency range from 50 MHz to 6 GHz. It can perform band-limited continuous average power measurements – i.e. measurements on a selected transmission channel – up to a signal bandwidth of 100 MHz.

Band-limited power measurements can significantly reduce the noise component measured in the signal, allowing power to be measured down to −130 dBm without sacrificing speed or accuracy. In comparison, conventional diode power sensors reach their limits at around −70 dBm due to the higher measured noise component.

Web-based control via LAN

The power sensor is controlled via a LAN web interface. Users can carry out continuous average power measurements, display traces to analyze pulsed signals, and perform ACLR measurements – a common mobile communications application. Predefined filters, e.g. in accordance with 3GPP specifications such as LTE, are provided. Diverse autoset functions simplify operation. For example, the measurement frequency and signal bandwidth can be determined and set automatically.

RF frontend captures vector-modulated signals

The R&S NRQ6 is based on an I/Q receiver and can be used as an RF frontend to capture I/Q signals. With the optional R&S NRQ6-K1 I/Q data interface, measured I/Q signals can be downloaded via LAN to a computer and analyzed. The R&S VSE vector signal explorer software from Rohde & Schwarz provides numerous measurement functions for vector signal analysis, such as EVM and ACLR.

Transmitter calibration in a straightforward, compact test setup

The R&S NRQ6 frequency-selective power sensor provides a compact, single-device solution for calibrating transmitters. Complex test setups involving a splitter and a spectrum analyzer are not required. Users can easily and precisely measure and calibrate the transmitter frequency response. Thanks to the excellent linearity of 0.02 dB across the entire dynamic range, it is also possible to calibrate power down to the lowest levels.

Rohde & Schwarz will be premiering the R&S NRQ6 frequency-selective power sensor at Mobile World Congress in Barcelona (hall 6, booth 6C40). The R&S NRQ6 will be available from Rohde & Schwarz in April 2018. For further information on the Rohde & Schwarz power sensor portfolio visit:
