New baseband signal generator from Rohde & Schwarz for UWB and aerospace & defense applications

Munich, October 13, 2008 — The new R&S AFQ100B from Rohde & Schwarz is an ideal signal source for developing and producing ultra-wideband (UWB) components. Using the R&S AFQ K264 software option, the instrument's intuitive interface makes it easy to generate all the test signals required for a WiMedia UWB band. Its large bandwidth, which is needed for UWB applications, also makes the R&S AFQ100B an excellent solution for the aerospace & defense market. The new baseband signal generator is able, for example, to deliver signals with modulated pulses or wide, nonlinear chirps for modern radar systems.

The WiMedia (ECMA-368) standard defines 14 bands each with a bandwidth of 528 MHz for UWB. This technology will be utilized for the next generation of Bluetooth® or for wireless USB. Thanks to its RF system bandwidth of 528 MHz, the R&S AFQ100B is an ideal tool for manufacturers of UWB baseband components such as receivers or I/Q modulators. The R&S AFQ-K264 option ensures that the WiMedia UWB signals output by the generator are configured to comply with the standard. The intuitive graphical display of the packet setup or hopping sequence, for example, supports the user in this task.

Multiple standards, e.g. UWB plus WiMAX and 3GPP, are increasingly being integrated into communications terminals. The R&S AFQ100B is able to generate a wide variety of digital communications standards in addition to WiMedia UWB. Rohde & Schwarz offers options for WCDMA, HSPA+, WiMAX, WLAN, LTE or other standards, which makes the new R&S AFQ100B an extremely versatile signal source.

The aerospace & defense market sector also utilizes digital baseband signals. Modern radar systems, for example, use short modulated pulses or wide, nonlinear chirps. The performance features of the R&S AFQ100B enable manufacturers of such systems to generate complex signals with short pulses and short rise and fall times. Pulse sequencer software from Rohde & Schwarz and the R&S AFQ-K6 option permit easy configuration of pulsed signals, including any type of analog or digital modulation. Plug-ins for inserting classified contents into the pulses are available. Many users in the A&D sector prefer generating the required signals themselves. To address this preference, Rohde & Schwarz offers a wide range of toolboxes for easy transfer of these signals to the R&S AFQ100B. The removable hard disk of the generator makes sure that confidential data never leaves the secured area.

The R&S AFQ100B baseband signal generator as well as the R&S AFQ-K264 option for ECMA-368 (UWB) and the R&S AFQ-K6 option for pulsed signals are now available from Rohde & Schwarz.
