Rohde & Schwarz NRPM OTA power measurement product for 5G and wireless gigabit components
The Rohde & Schwarz NRPM OTA power measurement product for 5G and wireless gigabit components is designed for measuring transmit power over-the-air interface.
The product enables users working in development and production to calibrate the output power of the antenna on a DUT and to test the DUT’s beamforming function.
The product works in the frequency range from 27.5 to 75 GHz and therefore covers the 28 GHz band currently being discussed for 5G, as well as the frequency range from 55 to 66 GHz for WLAN in line with IEEE 802.11ad and frequencies above 66 GHz in line with IEEE 802.11ay.
The antenna module is a simple, polarised Vivaldi antenna with an integrated diode detector for power measurements. It measures the relative power with a measurement accuracy better than 0.2 dB. Because the power is measured directly on the antenna, the user does not need any additional RF cables, which also eliminates complex compensation for cable loss.
The three-channel sensor module processes measurements from up to three antenna modules. If more than three antennas are needed for a test set-up, users can operate any number of sensor modules in parallel. The additional measurement points increase the measurement resolution during beamforming tests.
Power Viewer Plus PC software is available for evaluating and processing the measurement data. It can be used to visually monitor measurements on up to 12 channels and determine the average power.
