The Rohde & Schwarz NRP33T is a thermal power sensor that delivers precise power measurements from DC to 33 GHz. Engineered for research, production, and calibration environments, it combines low measurement noise with immunity to thermal drift, ensuring stable readings across demanding test scenarios. The sensor tolerates any modulation type and achieves measurement speeds three times faster than comparable solutions, with buffered mode performance exceeding 500 measurements/s. Its exceptional linearity of 0.007 dB and absolute power uncertainty as low as 0.040 dB make it ideal for high-accuracy RF and microwave applications.
