Rohde & Schwarz presents new test solutions for 5G base stations
Rohde & Schwarz is continuously extending its portfolio of test solutions for 5G base stations and the associated massive MIMO antenna arrays and amplifiers. Highlights include an OTA test solution with frontend modules specifically for the 5G FR2 range and a solution for speed-optimized tests of 5G base stations. Both are ideal for use in production. There is also a new, innovative test solution that allows developers to perform cross-channel measurements with up to 4x4 MIMO in the FR1 range.
As a leading manufacturer of wireless test solutions, Rohde & Schwarz has extended its portfolio for generation and analysis of 5G signal waveforms. For 5G base stations, RF test solutions for the 5G frequency ranges FR1 (450 MHz to 7.125 GHz) and FR2 up to 44 GHz will be demonstrated.
For over-the-air (OTA) tests on 5G base stations in the FR2 range, Rohde & Schwarz is launching a unique solution based on the R&S FE44 frontend modules, which support signal generation and analysis in the lower-frequency IF band. This enables low-loss transmission of 5G signals and the use of cost-effective T&M instruments by avoiding the need for equipment designed for the millimeterwave range. The R&S SMW200A vector signal generator generates the 5G signals, and the R&S FSVA3000 provides the right analysis functions. Both are ideal for 5G tests thanks to their excellent RF characteristics. The frontend modules can be mounted near the antennas of the DUT on the OTA test chamber.
In the transmit direction, the 5G signals generated in the IF band by the R&S SMW200A are upconverted to the FR2 range up to 44 GHz. This ensures that the high output power is generated exactly where it is needed. On the receive side, the R&S FE44A converts the FR2 signal at the antenna inputs down to the IF band and sends it with low attenuation losses to the R&S FSVA3000 for analysis. This solution is suitable for test systems in production.
