The new SMW200A high-end vector signal generator from Rohde & Schwarz offers maximum flexibility, outstanding performance and intuitive operation for generating complex, digitally modulated signals of high quality.
Its range of applications extends from single-path vector signal generator to multichannel MIMO receiver tester, thanks to versatile configuration options. The new SMW200A combines a baseband generator, RF generator and MIMO fading simulator in a single instrument.
The vector signal generator covers the frequency range from 100 kHz to 3 GHz or 6 GHz and features an I/Q modulation bandwidth of 160 MHz with internal baseband.
Exceptional modulation and RF characteristics make it the ideal instrument for developing high-end components, modules and complete products for wideband communications systems such as LTE-Advanced and WLAN IEEE 802.11ac. The generator performs particularly well in the verification of 3G and 4G base stations as well as aerospace / defence applications.
Two vector signal generators in a single unit
An optional second RF path is available for frequencies up to 6 GHz . The SMW200A can also be equipped with a with a maximum of two baseband and four fading simulator modules, giving you two full-featured vector signal generators in one unit. Fading scenarios such as 2x2 MIMO, 8x2 MIMO for TD-LTE and 2x2 MIMO for LTE-Advanced carrier aggregation can be simulated very easily.
For applications such as 3x3 MIMO for WLAN or 4x4 MIMO for LTE-FDD, more than two RF sources are needed. As well as the two internal RF paths provided, compact SGS100A signal generator modules can be connected as additional RF sources and remotely controlled by the SMW200A. This solution takes up only five height units for 4x4 MIMO receiver tests and provides correctly encoded baseband signals, realtime channel simulation, AWGN generation and, if required, phase-locked coupling of multiple RF paths.
Wide range of options for digital communication standards
Options for all the important digital communications standards are available:
These standards run directly on the SMW200A without connecting to an external PC so you can vary signals or specific parameters quickly and easily. The SMW200A is multichannel-compatible, enabling you to create scenarios using different signals with very little effort, for example in order to test multistandard radio base stations.
Excellent signal quality ensures high accuracy
The excellent signal quality of the R&S SMW200A ensures high accuracy in spectral and modulation measurements. The SSB phase noise is –139 dBc (typ.) at 1 GHz (20 kHz offset). With regard to modulation quality, the SMW200A scores highly with an EVM of –49 dB (meas.) for WLAN IEEE 802.11ac signals as well as a 0.05 dB (meas.) I/Q modulation frequency response over 160 MHz bandwidth.
New touchscreen provides even more intuitive control
The SMW200A has many user-friendly features including a new touchscreen which allows users to control the instrument even more intuitively.
