The Rohde & Schwarz NRP-Z57 is a precision thermal power sensor engineered for accurate measurements across DC to 67 GHz with a dynamic range of 55 dB (–35 dBm to +20 dBm). Built on an industry-proven DC-coupled thermoelectric test cell, it delivers outstanding linearity of 0.007 dB (0.16%)—surpassing conventional commercial products by a factor of 10 across the entire frequency range. The sensor handles any modulation type and achieves measurement speeds exceeding conventional instruments by a factor of three, with triggered measurements and buffered operation exceeding 500 measurements/s.
