LTE signal generators with MIMO support

Single-box testing with full standards compliance

Rohde & Schwarz has added channel coding and MIMO precoding for up to four transmit antennas to its signal generators for 3GPP LTE (long-term evolution), for both uplink and downlink. Mobile equipment manufacturers can use the generators as a single-point source for 2x2 MIMO signals with realtime fading; they can also supply fully-standards-compliant RF or baseband signals. Both the R&S SMU200A vector signal generator and the R&S AMU200A baseband signal generator now inlcude 2x2 MIMO fading in realtime. Both one-box solutions support the ITU fading profiles defined for 3GPP LTE including the correlation between the fading paths. Since the signal generators provide 3GPP TS 36.211 standard-compliant signals, the full scope of RF performance can be tested. No additional instruments or an external PC for signal calculation are required, which simplifies the test setup significantly. The new firmware update for MIMO precoding and channel coding for 3GPP LTE can be installed on the R&S SMU200A, R&S SMATE200A and R&S SMJ100A vector signal generators, as well as into the R&S AMU200A and R&S AFQ100A baseband signal generators. The new features will then be available with the internal R&S SMx-/R&S AMU-K55 options and the R&S WinIQSIM2 options (R&S SMU-/R&S SMJ-/R&S AMU-/ R&S AFQ-K255).
