The Rohde & Schwarz NRP-Z58 is a thermal power sensor delivering precise measurements across DC to 110 GHz. Built for aerospace, defense, and telecommunications applications, it combines wide dynamic range with ±0.5% accuracy and measurement speeds to 1000 readings/second. The sensor accepts both N-Type connectors for lower frequencies and 1.85 mm K-Type connectors above 50 GHz, integrating directly with Rohde & Schwarz NRP Series Power Meters via USB interface.
