Rohde & Schwarz R&S NRP-Z11 RF Power Sensor 8 GHz Wide Dynamic Range

The pre-owned R&S NRP-Z11 squeezes metrology-grade average, peak and statistical power measurement into a rugged, thumb-sized sensor that spans 10 MHz to 8 GHz without range switching.

Three-path diode technology delivers a seamless 90 dB dynamic span and better than ±0.05 dB linearity, so attenuator sweeps, amplifier gain checks and wireless-module calibrations finish in a single pass. An on-board FPGA streams up to 1 500 samples per second to an NRX or NRP2 meter (or directly via SCPI when powered), slashing calibration and production takt time while preserving traceable accuracy across temperature and frequency.

Shipped fully tested, freshly calibrated and firmware-current, this sensor offers an immediate, cost-efficient path to precise RF power metering backed by Rohde & Schwarz reliability.

Industry Background & Resource Sourcing

Over the past two decades, rapid advances in China’s radio-frequency sector have shortened production-line refresh cycles to roughly 3–5 years. Leveraging long-term partnerships with equipment OEMs, research institutes, and calibration labs, TESTRO acquires traceable, well-maintained decommissioned or replacement units. Every instrument undergoes a five-step technical check and third-party calibration before entering stock, ensuring reliable performance data.
