R&S enables test flexibility at lower cost

Channel coding and MIMO precoding for up to four transmit antennas have been added to Rohde & Schwarz firmware for signal generators for 3GPP LTE (uplink and downlink). By including the latest revisions of the 3GPP LTE standard in the firmware, Rohde & Schwarz is enabling greater test flexibility at lower cost.

In performance testing, for example, both the R&S SMU 200A vector signal generator and the R&S AMU 200A baseband signal generator generate standard-compliant test signals, including 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.

Less is more
Manufacturers no longer require external fading hardware or control software for testing 3GPP LTE mobile stations because the signal generators provide 3GPP TS 36.211 standard-compliant signals. 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).

Rohde & Schwarz is one of the exhibitors in the upcoming IIC-China 2008.
