R&S NRP90S(N) from Rohde & Schwarz is a diode power sensor for power measurements up to 90 GHz. The new instruments offer a frequency range of 50 MHz to 90 GHz with a dynamic range from -70 dBm to 20 dBm along with high measurement speeds of 50,000 measurements per second. The higher measurement frequency of sensors allows the T&M instrument to cover the latest spectrum allocation for 5G FR2-2 up to 71 GHz, satellite communications in both the 71 GHz to 76 GHz band and the 81 GHz to 86 GHz band, automotive radars operating from 76 GHz to 81 GHz, as well as other lower frequency wireless transmission technologies. The NRPxxS power sensors have a portable form factor and flexible operating modes that makes it suitable for both local and remote installation in maintenance or monitoring applications.

According to the company, the diode technology enables extremely fast and accurate power measurements. The diode technology offers high sensitivity and comes in a compact and lightweight portable instrument. It also enables high-speed power measurements for all frequencies above 67 GHz in 5G, automotive radar and satellite communications applications including the entire E band.

The new instruments offer a dynamic range from -70 dBm to 20 dBm along with high measurement speeds of 50,000 measurements per second. It significantly cuts the test time due to its high power measurement dynamic range of 35 dB.

The NRPxxS power sensor series is ideal for both local and remote installation in maintenance or monitoring applications due to its portable form factor and flexible operating modes. Furthermore, the device is compatible with the company’s existing products including an R&S NRX power meter, selected Rohde & Schwarz signal generators and analyzers, or a PC with the R&S NRPV virtual power meter installed. The devices support the USBTMC protocol industry standard for easy integration into test systems. The R&S NRPxxSN also includes an Ethernet interface to support remote LAN operation.
