The R&S NRP-Z21 18 GHz three-path diode universal power sensor is suitable for numerous applications because it supports continuous average, burst average, timeslot average, gate average and trace measurements. Featuring outstanding performance and high measurement speed and accuracy, the sensors can be used to perform precise average power measurements on modern wireless standard signals such as LTE, 3GPP, GSM, WiMAX™ and WLAN. For detailed analysis of GSM signals, for example, the sensors offer additional measurement functions such as the timeslot mode and trace mode with a video bandwidth of 100 kHz. Specifications. Frequency range: 10 MHz to 18 GHz. Power range: 200 pW to 200 mW (–67 dBm to +23 dBm). Maximum average power: 400 mW. Peak envelope power: 1 W (PK, 10 µs). Connector type: N. Impedance matching (SWR): 10 MHz to 2.4 GHz < 1.13, > 2.4 GHz to 8.0 GHz < 1.20, > 8.0 GHz to 18.0 GHz < 1.25. Rise time Video BW: < 8 µs > 50 kHz. Zero offset (typ.): 64 pW. Noise (typ.): 40 pW. Uncertainty for power measurements at +20 °C to +25 °C: 0.047 dB to 0.128 dB (absolute), 0.022 dB to 0.110 dB (relative).
