The Rohde & Schwarz NRP6A is an average power sensor delivering precision measurements across 8 kHz to 6 GHz with a dynamic range spanning 100 pW to 200 mW (−70 dBm to +23 dBm). Built on three-path diode sensor architecture, it achieves 93 dB dynamic range for both CW and modulated signals, making it essential for power characterization in EMC testing, signal validation, and broadband RF applications.
