Firmware upgrades wireless simulation

A Rohde and Schwarz product story

Edited by the Electronicstalk editorial team May 8, 2006

New firmware allows the R and S SMU200A, SMATE200A and SMJ100A signal generators to operate in accordance with the IEEE802.16-2004, 802.16e and WiBRO standards.

Equipped with the R and S SMx-K49 option, the R and S SMU200A, R and S SMATE200A and R and S SMJ100A signal generators operate in accordance with the IEEE802.16-2004, 802.16e and WiBRO standards.

The new firmware update provides additional important functionalities for receiver and component tests of WiMAX equipment, including multiple zones, PUSC and FUSC permutations as well as space time coding and ranging.

There are few technologies that are undergoing as much change as WiMAX.

Rohde and Schwarz is a step ahead of this trend and offers component and receiver manufacturers a reliable reference solution.

Users can regularly update their software options with new firmware to meet the latest technological requirements.

The R and S SMx-K49 option allows users to generate WiMAX signals with 511 frames.

Signal generators can thus provide complete PN9 sequences for bit error ratio measurements and ensure that test results are correct.

Plus, the R and S SMU200A is the world's only instrument that optionally offers an integrated fading simulator and a two-path design.

The new firmware update also makes it possible to generate signals with fully utilised subchannel allocation (FUSC) and partially utilised subchannel allocation (PUSC) permutations.

These two methods allocate logical channels to physical channels.

Furthermore, users can generate signals with multiple zones.

Space time coding allows the receiver to process signals from more than one transmit antenna.

The purpose of transmit diversity generated in this way is to increase datarates.

The new tests can be enabled for all signal generators of the R and S SMx family by means of a firmware update.

The R and S SMU200A is ideal for tests on WiMAX equipment, with typical single sideband phase noise of -135dBc (1GHz, 20kHz offset) and typical wideband noise of -151dBc (1GHz, more than 10MHz offset) representing the best values in its class.
