The Rohde & Schwarz NRP40T is a thermal power sensor for precision measurements from DC to 40 GHz. It delivers high-accuracy power detection across demanding applications including radar systems, advanced communications, and microwave component testing. The sensor minimizes measurement noise and resists environmental thermal drift, ensuring stable readings. Excellent impedance matching reduces reflection-induced uncertainty, while the sophisticated coaxial connector prevents relative movement between sensor and device under test. Operation integrates with compatible Rohde & Schwarz power meters or direct PC control via USB or LAN interfaces.
