Rohde & Schwarz NRP-Z24 Power Sensor

The Rohde & Schwarz NRP-Z24 is a three-path diode power sensor delivering high-accuracy measurements across DC to 18 GHz with dynamic range up to 90 dB. It operates standalone via USB connection to PC or laptop, or integrates with the R&S NRP2 base unit. The sensor measures average power, burst average, timeslot average, gate average, and trace data with specialized functions for modern wireless standards including LTE, 3GPP, GSM, WiMAX, and WLAN.
