Rohde & Schwarz NRP Power Meter

The Rohde & Schwarz NRP Power Meter series delivers high-precision RF and microwave power measurements across DC to 110 GHz, depending on sensor selection. Built on a modular architecture combining intelligent power sensors with an optional base unit, it measures continuous average, burst average, timeslot average, gate average, and trace signals with accuracy down to –70 dBm and up to +45 dBm. The platform excels at characterizing broadband modulated signals, signal bursts, and individual timeslots in time division systems—essential for modern wireless standards and emerging technologies.
