Key Facts The R&S®SMW-B90 phase coherence option allows the use of a common local oscillator (LO) for multiple RF signals, making it possible to generate phase-coherent RF carriers. Frequencies from 200 MHz to 6 GHz can be coupled. For an R&S®SMW200A vector signal generator that is configured as a dual-path instrument with two internal RF signal generators, the R&S®SMW-B90 option ensures a stable relative phase between the two RF outputs. Additionally, the R&S®SMW-B90 hardware option has a LO IN and LO OUT connector. The LO signal that is generated inside one signal generator can be distributed to further instruments via these connectors. The R&S®SMW-B90 option addresses all applications where a precise phase relationship between two or more RF signals is required, e.g.:
  • Beamforming as used in digital communications standards (e.g. WLAN, WiMAX™)
  • Performance evaluation of algorithms used in MIMO receivers for determining whether they are able to compensate defined phase differences between the antennas
  • Design of phased array antennas
  • Test of modules that use differential RF (e.g. differential amplifiers)
