The Rohde & Schwarz NRP-Z28 is a level control sensor for precise power measurement and signal conditioning across 10 MHz to 18 GHz. It integrates a power splitter that divides RF signals into two equal parts, simultaneously feeding power to a Device Under Test while monitoring output levels. This dual-path architecture eliminates the need to disconnect the DUT for power measurements, making it ideal for permanent test setup integration. Built on Smart Sensor Technology, the NRP-Z28 operates as an independent instrument with onboard calibration data fully characterized across frequency, level, and temperature ranges. No zeroing is required.
