Firmware enables single-box WiMAX testing

A new option for worldwide interoperability for microwave access (WiMAX) expands the range of functions of the high-end R and S FSQ signal analyser.

A new option for worldwide interoperability for microwave access (WiMAX) expands the range of functions of the high-end R and S FSQ signal analyser.

New application firmware permits TX measurements on OFDM signals in accordance with the IEEE802.16 2004 standard.

Rohde and Schwarz provides the only WiMAX test solution that consists of just one box.

It records and analyses the signal and graphically represents the results.

Optional I/Q inputs allow direct signal analysis in the baseband.

With a data transmission rate of up to 75Mbit/s, WiMAX is projected to replace cable-bound solutions such as DSL.

To support this new standard, Rohde and Schwarz now offers the FSQ-K92 application firmware as an option for its FSQ signal analyser.

The new option enables the high-end signal analyser to perform transmitter measurements on OFDM signals in accordance with the IEEE802.16-2004 standard as well as further tests for the design of WiMAX applications.

The signal analyser records and analyses the signal, which may range from 1.5 to 28MHz.

It then outputs the results in a table or graphically displays them.

All parameters that are key to describing signal quality can be seen at a glance, including EVM values, frequency drift or I/Q errors.

This allows designers to exactly characterise the modulation quality and other parameters such as adjacent channel power or spectrum mask of their WiMAX application.

Only the solution from Rohde and Schwarz permits measurements to be performed on WiMAX signals by using just one instrument and offers additional I/Q inputs for direct analysis in the baseband.

Moreover, the R and S FSQ features outstanding characteristics in spectrum analysis.

Depending on the model, the R and S FSQ can be used for frequencies up to 40GHz.
