The compact, robust R&S® NRP2 base unit with color display supports up to four R&S® NRP-Zxx or NRPxxS/SN power sensors and all sensor-dependent measurement functions. Measured values are displayed numerically or graphically, depending on the measurement function. The window-based user interface allows simple, intuitive operation; the base unit can be remotely controlled via Ethernet, GPIB, or USB.
