4 GHz RF Power Meter Directional Power & VSWR Meter Rohde & Schwarz R&S NRT2

The pre-owned R&S NRT2 combines a high-dynamic-range directional watt-meter with built-in VSWR computation, enabling engineers to measure forward power, reflected power and mismatch on transmitters from 25 MHz to 4 GHz without external couplers or re-cabling.

When paired with NRT-Z sensors, it delivers up to 60 dB instantaneous range — from sub-milliwatt levels to 30 W — while displaying FWD, REV and VSWR simultaneously on a bright 5-inch touchscreen. Fast-list acquisition of approximately 1,000 samples per second reduces production alignment time, and onboard limit monitoring flags out-of-spec modules in real time. USB/LAN (plus optional GPIB and analog outputs) support SCPI automation in ATE racks, while sensor EEPROM auto-calibration maintains < 1 dB uncertainty across temperature and frequency.

Shipped fully tested, freshly calibrated and with current firmware, this NRT2 provides a cost-efficient solution for accurate power and return-loss measurements backed by Rohde & Schwarz reliability.
