The Rohde & Schwarz NRP-Z98 is a precision level control sensor that splits incoming RF signals into two equal paths: one for measurement and one for output to the Device Under Test. Operating across 9 kHz to 6 GHz, it monitors signal generator output power in real time and enables automatic level correction when paired with compatible Rohde & Schwarz signal generators. The sensor eliminates uncertainties from cable losses and load mismatches, bridging distances up to 1.2 meters via an integrated low-loss microwave cable. Measurements display on compatible base units, signal generators, or PC-based software.
