Rohde and Schwarz NRP-Z52 Thermal Power Sensor, 300 nW to 100 mW, DC to 33 GHz

The Rohde & Schwarz NRP-Z52 is a thermal power sensor engineered for precise power measurements across DC to 33 GHz. It delivers true RMS power readings from 300 nW to 100 mW, making it suitable for demanding R&D, manufacturing, and quality assurance environments where accurate RF and microwave characterization is essential.

Technical Specifications

• 300 nW to 100 mW (-65.2 dBm to +20 dBm) Frequency Range:


• DC to 33 GHz Detector Technology:


• Thermal detection element for broad bandwidth operation Measurement Capabilities:


• True RMS power measurement for non-sinusoidal signals


• Modulation mode support for various signal conditions


• Offset power measurement capability


• Zeroing functionality for reference point establishment and drift compensation

Key Features Thermal detection architecture enables high-accuracy readings across the full frequency spectrum without modulation-dependent measurement errors. The sensor supports offset and zeroing functions for relative power assessments and reference compensation. Design accommodates modern communication systems through multimodulation signal compatibility.

Typical Applications Research and development characterization of RF/microwave power levels. Manufacturing and quality control power validation. System integration environments requiring repeatable, traceable thermal power measurements.

Compatibility & Integration The NRP-Z52 interfaces with Rohde & Schwarz power meters supporting the NRP sensor family. The meter provides all power and control signaling to the sensor. Standard RF connectors (type varies by configuration) enable field deployment. Sensor-specific calibration data is recognized and managed by compatible host instruments.
