The Rohde & Schwarz NRP8S(N) is a three-path diode power sensor engineered for precise RF power measurements across 10 MHz to 8 GHz. This self-contained, fully characterized instrument delivers high accuracy and speed, particularly at low power levels. The three-path architecture minimizes measurement noise and enables a dynamic range of 93 dB with a lower measurement limit of –70 dBm.
