Power Sensors Take Measurements To the Next Level

Feb. 26, 2021
Rohde & Schwarz's three-path diode power sensors enable fast and accurate power measurements with a high-sensitivity, portable instrument.

Rohde & Schwarz has increased the maximum measurable frequency of its three-path diode power sensors to an unrivaled 67 GHz. The three-path technology enables extremely fast and accurate power measurements with a high-sensitivity, portable instrument of minimum size and weight. This frequency extension makes high-speed power measurements possible for additional applications such as IEEE 802.11ay and 802.11ad WiGig Wireless LAN, millimeter-wave terrestrial short-distance communication links, and satellite-satellite links operating at 60 GHz.


The NRP67S and NRP67SN power sensors introduce a frequency range unprecedented in a diode power sensor, reaching from 50 MHz all the way up to 67 GHz. Combined with the advantages of the three-path diode technology, a wide dynamic range from -70 to 20 dBm, and a high measurement speed of 10,000 measurements per second, users benefit from extremely fast power measurements with unsurpassed accuracy and dynamic range previously not possible at these frequencies.


With the latest WiFi and Wireless HD standards operating above 57 GHz now supported, as well as practically all other wireless communication technologies in use, the R&S NRP67S/SN is a near-universal tool for wireless infrastructure power measurements.


All NRPxxS power sensors with their portable format are ideal for installation, maintenance, or monitoring applications, both locally or remotely. They can be used to connect to an R&S NRX power meter, selected Rohde & Schwarz signal generators and analyzers or a PC with the NRPV virtual power meter software installed. In addition, the NRPxxSN includes an Ethernet interface to support remote operation via LAN. The devices support the industry-standard USBTMC protocol, making integration into test systems easy.
