R&S improves vector signal generator with three new options

Posted: 12 Mar 2015 ?? ?Print Version ?Bookmark and Share

Keywords:SMW200A? signal generator? 5G? LTE?

Rohde & Schwarz has added three options to its SMW200A, a high-end vector signal generator with microwave frequency ranges from 100kHz to 12.75GHz, 100kHz to 31.8GHz and 100kHz to 40GHz. An option covering the range between 100kHz and 20GHz has been available since the summer of 2014.

The R&S SMW200A is the only microwave signal generator on the market to combine a base band generator and RF generator with fading, AWGN and MIMO capabilities in a single box. As a result, it supports numerous challenging aerospace and defence and wireless communications applications.

Radar and satellite component and module tests

The 40GHz version of the R&S SMW200A enables users to completely cover the K and Ka bands. The generator's integrated base band offers an RF modulation bandwidth of 160MHz with excellent I/Q flatness and EVM, making it possible to generate signals of the highest modulation quality in the microwave range. It is even easy to generate CW signals with multiple carriers for component tests and wideband QAM-modulated carriers for satellite receiver tests.

R&S SMW200A

Complex signals for 5G test setups

The R&S SMW200A is helping developers identify potential technologies for accessing 5G wireless networks. The new frequency options enable the instrument to cover the frequency ranges that are currently the focus of 5G development. Its internal base band section can handle all important digital communications standard including LTE Releases 8 to 11. The signal bandwidth of the R&S SMW200A can even reach 2GHz when external I/Q signals are used.

Modulated, phase-coherent signals up to 40GHz

Beamforming applications are used to measure active antenna systems such as phased arrays. This requires high quality, phase coherent test signals. The LO coupling of the R&S SMW200A now makes it possible to set up a compact system with up to three phase coherent outputs up to 40GHz. In addition to the R&S SMW200A, the setup employs two combinations of the R&S SGS100A and R&S SGU100A as additional RF paths up to 40GHz. The additional signal sources can be easily controlled via the R&S SMW200A GUI.

Extensive test applications for wireless communications

Many wireless communications applications require complex microwave test signals. The R&S SMW200A now also generates high quality digitally modulated signals up to 40GHz for direct microwave link applications. If, for example, a 12.75GHz and a 6GHz RF path are installed in a single instrument, it is fast and easy to carry out the complex conformance tests specified by many telecommunications standards. The instrument's integrated test case wizard enables users to configure even complex WCDMA and LTE test scenarios such as blocking tests at the push of a button. The 12.75GHz frequency option also offers a wear free electronic attenuator.

The new R&S SMW-B112, R&S SMW-B131 and R&S SMW-B140 frequency options are available now.
