Key facts
The R&S®NRQ6 combines the accuracy of a power meter with excellent dynamic range
The R&S®NRQ6 is based on receiver technology and can perform band-limited power measurements down to -130 dBm. The R&S®NRQ6 combines high-precision with high-speed measurements beyond the limits of currently available power meters. In addition to conventional continuous average measurements, the R&S®NRQ6 has a trace display function and also performs ACLR measurements. The optional R&S®NRQ6-K1 I/Q data interface, R&S®NRQ6-K2 power servoing and R&S®NRQ6-K3 phase coherent measurements options complete the R&S®NRQ6 as new category of test and measurment devices.

The R&S®NRQ6 as a standalone RF frontend
The R&S®NRQ6 can be used as a standalone RF frontend to capture vector-modulated I/Q signals. With the optional R&S®NRQ6-K1 I/Q data interface, captured I/Q data can be read out using SCPI commands. The data is demodulated and analyzed using external software, e.g. R&S®VSE. With the R&S®NRQ6 version 2.10 and the R&S®VSE version 1.70, direct data aquisition and control is possible.
5G NR measurement with R&S®NRQ6 and R&S®VSE
In component test applications non-linear characteristics of DUT´s make it difficult to set up a specific output power. The R&S®NRQ6-K2 power servoing option enables a dedicated serial communications channel over the trigger connectors between R&S®NRQ6 and R&S®SGT100A. The desired power will be set in several iterations and is finished typically in 1 ms to 1.5 ms.
Power servoing with R&S®NRQ6 and R&S®SGT100A
In the power servoing setup the R&S®NRQ6 can perform also power measurements without disconnecting, just by remote control commands.
Calibration of multiple active antenna modules for beamforming
The synchronous phase coherent measurements (option R&S®NRQ6-K3) are based on a primary/secondary relationship between two or more R&S NRQ6. The primary forwards the local oscillator signal (LO) and its clock signal (CLK) to the secondary(ies) and triggers the secondary(ies). The RF phases can be measured at up to 8 ports, where the typical uncertainty is only 0.1 degree at an power of -60 dBm.
R&S®NRQ6 multichannel phase difference measurement
Results of a measurement with one R&S®NRQ6 as primary (only used for distribution of TRG, CLK and LO signals) and eight R&S®NRQ6 as secondaries.
Beyond limits of conventional diode power sensors
Every diode based power meter works without band limitation in the specified frequency range. Precise measurement of low-power signals requires averaging of multiple measurement samples and this increases the measurement time. The diode based power meter technology is mature, and therefore only limited product innovations are possible. The receiver technology based R&S®NRQ6 has significantly increased the measurement speed for low-power signals.
Measurement time comparison for a CW signal
With the R&S®NRQ6 the measurement time is reduced e.g. by a factor of ca. 20.000 in comparison to the NRP8S for a -50 dBm CW signal.
