Flexible R&S SMW200A High-End Vector Signal Generator Creates
Scenarios for Highest Demands
- The new R&S SMW200A high-end vector signal generator from Rohde & Schwarz
combines maximum flexibility, outstanding performance and intuitive operation to outperform
all comparable solutions available on the market. It is the perfect tool for generating complex,
digitally modulated signals of high quality. Thanks to versatile configuration options, its
range of applications extends from single-path vector signal generator to multichannel MIMO
Munich, April 26, 2013 — The new R&S SMW200A
high-end vector signal generator from Rohde & Schwarz 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 ideal 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 especially well when it comes to the verification of 3G and 4G base stations as well
as aerospace and defense applications.
R&S SMW200A can be equipped with an optional second RF path for frequencies up to 6 GHz
and with a maximum of two baseband and four fading simulator modules, giving users two full-featured
vector signal generators in a single 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. Until now, this
has required complex setups consisting of multiple instruments.
More than two RF sources
are required for applications such as 3x3 MIMO for WLAN or 4x4 MIMO for LTE-FDD. In addition
to the two internal RF paths provided, highly compact R&S SGS100A signal generator
modules can be connected as additional RF sources and remotely controlled by the R&S 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.
Options for every important digital communications standard
are available from the start: LTE, LTE-Advanced, 3GPP FDD/HSPA/HSPA+, GSM/EDGE/EDGE Evolution,
TD-SCDMA, CDMA2000®/1xEV-DO and WLAN IEEE 802.11a/b/g/n/ac. The standards run directly on the
R&S SMW200A ‒ without having to connect an external PC, making it possible to vary
signals or specific parameters quickly and easily. This simplifies troubleshooting on the DUT
and also saves time. Because the R&S SMW200A is multichannel-compatible, developers can
even create scenarios using different signals with minimal effort, for example, in order to
test multistandard radio base stations.
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). In terms of modulation quality, the R&S SMW200A
scores top marks 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. These characteristics
help developers to be confident that their products are of outstanding quality.
The R&S SMW200A
also comes with a cleverly devised operating concept. The new touchscreen allows users to control
the instrument even more intuitively with the tried and tested Rohde & Schwarz
block diagram as key operating element to visualize the signal flow. Help functions are provided
to quickly achieve success. Presets are provided for all important digital standards and fading
scenarios. LTE and UMTS test case wizards simplify complex base station conformance testing
in line with the 3GPP specification.
Wolfgang Kernchen, Director of the Signal Generators,
Audio Analyzers and Power Meters Subdivision at Rohde & Schwarz said, "We want
our new flagship product to give customers an instrument that makes their work easier thanks
to its outstanding performance and intelligent operating assistance features. At the same time,
our unique, compact solution is highly scalable and future-ready. This gives developers the
ideal framework to ensure their products comply with today's sophisticated communications standards
and those of the future, so that their products can be made ready for the market as quickly
The new high-end R&S SMW200A vector signal generator is now available
from Rohde & Schwarz.
