The instrument is aimed at R&D designers of modern radar systems and equipment that implement modern communication standards like 5G or IEEE 802.11ad which require instruments with a wide signal generation bandwidth.

With the introduction of the R&S SMW-B9 wideband baseband generation option, Rohde & Schwarz is providing leading-edge baseband capabilities in its R&S SMW200A high-end vector signal generator. The R&S SMW-B9 option extends RF modulation bandwidth to 2 GHz enabling R&D engineers to generate signals with extreme wide bandwidth up to microwave frequencies. No other vector signal generator in the market offers a fully calibrated wideband solution up to 40 GHz in a single device.

The R&S SMW-B9 option can be integrated twice, which makes it possible to generate two independent wideband signals with any type of modulation up to 20 GHz with one instrument. The test setup capabilities support challenging applications in the aerospace & defense and wireless communication area. Developers of advanced radar systems and emerging communication standards such as 5G cellular and IEEE 802.11ad will be among the first beneficiaries.

In radar and aerospace designs, the 40-GHz version of the R&S SMW200A enables users to completely cover the K and Ka bands. The 2-GHz RF modulation bandwidth makes it possible to generate dedicated pulses with minimized pulse width and rise time or linear frequency modulated signals up to 2 GHz.

For development teams working on identifying potential 5G wireless access technologies, the R&S SMW200A equipped with option R&S SMW-K114 (5G Candidates) provides powerful capabilities in a single instrument. Potential 5G candidate waveforms such as FBMC, UFMC, GFDM or f-OFDM can be created directly on the instrument allowing the user to analyze and understand design challenges. Typical test scenarios such as co-existence tests with LTE or wide bandwidth 5G signal generation in the microwave range are now possible with one single unit.

The performance of the R&S SMW200A also makes the instrument ideal for developers of devices and components that must comply with IEEE 802.11ad, the latest WLAN standard. The new option R&S SMW-K141 enables the generation of IEEE 802.11ad signals with a symbol rate of 1.76 Gsample/s in single carrier mode, requiring 2 GHz of bandwidth.
