Measurement solutions for uplink and downlink signals

Click2Contact

The R&S SMx-K55 3GPP LTE option for Rohde & Schwarz signal generators offers downlink and uplink functionalities. The SMU200A, SMJ100A and SMATE200A can generate high-quality 3GPP LTE signals for tests on components and receivers of base stations and mobile phones.

Channel coding, MIMO precoding for up to four transmission antennas as well as 2x2 MIMO fading in real time are also available.

The software is installed directly on the instruments. Users can call up predefined scenarios or set the parameters of reference symbols as well as control, synchronisation and data channels as required. Plus, users can configure subframes independently of one another.

The FSQ and FSG signal analysers are now capable of analysing transmitter modules of forthcoming 3GPP LTE mobile phones. For the uplink, the FSQ-K101 option supports all typical measurements on digitally modulated signals by providing displays in graphical or tabular form.

The 3GPP LTE options are initially being implemented as PC software that externally drives the analysers. This allows the software to be adapted to new versions of the standard on short notice. After final adoption of the standard in 2008, the software is to be integrated into the analyser firmware.
