The R&S®SMW200A vector signal generator is the ideal tool for early 5G physical layer testing. By means of the R&S®SMW-K114 option, the R&S®SMW200A flexibly generates customized 5G air interface candidate signals.
The user can choose from various waveform types such as GFDM, FBMC, UFMC or f-OFDM and parameterize the signals as desired. Pulse shaping filters, subcarrier spacing and the number of carriers as well as used modulation and data content can be set. Preamble generation, a configurable cyclic prefix length and support for sparse code multiple access (SCMA) allow for testing of components or receivers with realistic pre-5G physical layer signals. Direct internal signal generation – without the need for any external PC software – helps to speed up the signal creation process.
Optionally, the R&S®SMW200A can also be equipped with a second signal generation path. This allows simultaneous generation of a 5G candidate signal and a legacy LTE signal from a single signal generator without complicated synchronization of multiple separate signal sources. Interdependencies between LTE and 5G are hence quickly simulated. And interference that occurs in the device under test (DUT) because of simultaneous presence of 5G and LTE are discovered easily.
